1. Data Science Memes

 

As a data scientist, you must be able to relate to the above meme. R is a popular language for statistical computing, while Python is a general-purpose language that is also widely used for data science. They both are the most used languages in data science having their own advantages.

 

 

 

Here is a more detailed explanation of the two languages:

• R is a statistical programming language that is specifically designed for data analysis and visualization. It is a powerful language with a wide range of libraries and packages, making it a popular choice for data scientists.
• Python is a general-purpose programming language that can be used for a variety of tasks, including data science. It is a relatively easy language to learn, and it has a large and active community of developers.

Both R and Python are powerful languages that can be used for data science. The best language for you will depend on your specific needs and preferences. If you are looking for a language that is specifically designed for statistical computing, then R is a good choice. If you are looking for a language that is more versatile and can be used for a variety of tasks, then Python is a good choice.

Here are some additional thoughts on R and Python in data science:

• R is often seen as the better language for statistical analysis, while Python is often seen as the better language for machine learning. However, both languages can be used for both tasks.
• R is generally slower than Python, but it is more expressive and has a wider range of libraries and packages.
• Python is easier to learn than R, but it has a steeper learning curve for statistical analysis.

Ultimately, the best language for you will depend on your specific needs and preferences. If you are not sure which language to choose, I recommend trying both and seeing which one you prefer.

We’ve been on Twitter for a while now and noticed that there’s always a new tool or app being announced. It’s like the world of tech is constantly evolving, and we’re all just trying to keep up.

Although we are constantly learning about new tools and looking for ways to improve the workflow. But sometimes, it can be a bit overwhelming. There’s just so much information out there, and it’s hard to know which tools are worth your time.

So, what should we do to efficiently learn about evolving technology? We can develop a bit of a filter when it comes to new tools. If you see a tweet about a new tool, first ask yourself: “What problem does this tool solve?” If the answer is something that I’m currently struggling with, then take a closer look.

Also, check out the reviews for the tool. If the reviews are mostly positive, then try it. But if the reviews are mixed, then you can probably pass. Just

Just remember to be selective about the tools you use. Don’t just install every new tool that you see. Instead, focus on the tools that will actually help you be more productive.

And who knows, maybe you’ll even be the one to announce the next big thing!

• Practice makes perfect. The best way to learn machine learning is by practicing. Try to build your own machine learning models and see how they perform.

With time and effort, you can overcome the confusion and learn to use machine learning to solve real-world problems.

 

3. Statistics Meme

Here are some fun examples to understand about outliers in linear regression models:

Outliers are like weird kids in school. They don’t fit in with the rest of the data, and they can make the model look really strange.
Outliers are like bad apples in a barrel. They can spoil the whole batch, and they can make the model inaccurate.
Outliers are like the drunk guy at a party. They’re not really sure what they’re doing, and they’re making a mess.

So, how do you deal with outliers in linear regression models? There are a few things you can do:

• You can try to identify the outliers and remove them from the data set. This is a good option if the outliers are clearly not representative of the overall trend.
• You can try to fit a non-linear regression model to the data. This is a good option if the data does not follow a linear trend.
• You can try to adjust the model to account for the outliers. This is a more complex option, but it can be effective in some cases.

Ultimately, the best way to deal with outliers in linear regression models depends on the specific data set and the goals of the analysis.

 

4. Programming Language Meme

 

Java and Python are two of the most popular programming languages in the world. They are both object-oriented languages, but they have different syntax and semantics.

Here is a simple code written in Java:

And here is the same code written in Python:

As you can see, the Java code is more verbose than the Python code. This is because Java is a statically typed language, which means that the types of variables and expressions must be declared explicitly. Python, on the other hand, is a dynamically typed language, which means that the types of variables and expressions are inferred by the interpreter.

The Java code is also more structured than the Python code. This is because Java is a block-structured language, which means that statements must be enclosed in blocks. Python, on the other hand, is a free-form language, which means that statements can be placed anywhere on a line.

So, which language is better? It depends on your needs. If you need a language that is statically typed and structured, then Java is a good choice. If you need a language that is dynamically typed and free-form, then Python is a good choice.

Here is a light and funny way to think about the difference between Java and Python:

• Java is like a suit and tie. It’s formal and professional.
• Python is like a T-shirt and jeans. It’s casual and relaxed.
• Java is like a German car. It’s efficient and reliable.
• Python is like a Japanese car. It’s fun and quirky.

Ultimately, the best language for you depends on your personal preferences. If you’re not sure which language to choose, I recommend trying both and seeing which one you like better.

 

Git pull and git push are two of the most common commands used in Git. They are used to synchronize your local repository with a remote repository.

Git pull fetches the latest changes from the remote repository and merges them into your local repository.

Git push pushes your local changes to the remote repository.

Here is a light and funny way to think about git pull and git push:

• Git pull is like asking your friend to bring you a beer. You’re getting something that’s already been made, and you’re not really doing anything.
• Git push is like making your own beer. It’s more work, but you get to enjoy the fruits of your labor.
• Git pull is like a lazy river. You just float along and let the current take you.
• Git push is like whitewater rafting. It’s more exciting, but it’s also more dangerous.

Ultimately, the best way to use git pull and git push depends on your needs. If you need to keep your local repository up-to-date with the latest changes, then you should use git pull. If you need to share your changes with others, then you should use git push.

Here is a joke about git pull and git push:

Why did the Git developer cross the road?

To fetch the latest changes.

User Experience Meme

Bad user experience (UX) happens when you start off with high hopes, but then things start to go wrong. The website is slow, the buttons are hard to find, and the error messages are confusing. By the end of the experience, you’re just hoping to get out of there as soon as possible.

Here are some examples of bad UX:

• A website that takes forever to load.
• A form that asks for too much information.
• An error message that doesn’t tell you what went wrong.
• A website that’s not mobile-friendly.

Bad UX can be frustrating and even lead to users abandoning a website or app altogether. So, if you’re designing a user interface, make sure to put the user first and create an experience that’s easy and enjoyable to use.

The Python Requests library is the go-to solution for making HTTP requests in Python, thanks to its elegant and intuitive API that simplifies the process of interacting with web services and consuming data in the application.

With the Requests library, you can easily send a variety of HTTP requests without worrying about the underlying complexities. It is a human-friendly HTTP Library that is incredibly easy to use, and one of its notable benefits is that it eliminates the need to manually add the query string to the URL.

HTTP Methods

When an HTTP request is sent, it returns a Response Object containing all the data related to the server’s response to the request. The Response object encapsulates a variety of information about the response, including the content, encoding, status code, headers, and more.

GET is one of the most frequently used HTTP methods, as it enables you to retrieve data from a specified resource. To make a GET request, you can use the requests.get() method.

>> response = requests.get(‘https://api.github.com’)

The simplicity of Requests’ API means that all forms of HTTP requests are straightforward. For example, this is how you make an HTTP POST request:

>> r = requests.post(‘https://httpbin.org/post’, data={‘key’: ‘value’})

POST requests are commonly used when submitting data from forms or uploading files. These requests are intended for creating or updating resources, and allow larger amounts of data to be sent in a single request. This is an overview of what Request can do.

Real-world applications

Requests library’s simplicity and flexibility make it a valuable tool for a wide range of web-related tasks in Python, here are few basic applications of requests library:

1. Web scraping:

Web scraping involves extracting data from websites by fetching the HTML content of web pages and then parsing and analyzing that content to extract specific information. The Requests library is used to make HTTP requests to the desired web pages and retrieve the HTML content. Once the HTML content is obtained, you can use libraries like BeautifulSoup to parse the HTML and extract the relevant data.

2. API integration:

Many web services and platforms provide APIs that allow you to retrieve or manipulate data. With the Requests library, you can make HTTP requests to these APIs, send parameters, headers, and handle the responses to integrate external data into your Python applications. We can also integrate the OpenAI ChatGPT API with the Requests library by making HTTP POST requests to the API endpoint and send the conversation as input to receive model-generated responses.

3. File download/upload:

You can download files from URLs using the Requests library. It supports streaming and allows you to efficiently download large files. Similarly, you can upload files to a server by sending multipart/form-data requests. requests.get() method is used to send a GET request to the specified URL to download large files, whereas, requests.post() method is used to send a POST request to the specified URL for uploading a file, you can easily retrieve files from URLs or send files to a server. This is useful for tasks such as downloading images, PDFs, or other resources from the web or uploading files to web applications or APIs that support file uploads.

4. Data collection and monitoring:

Requests can be used to fetch data from different sources at regular intervals by setting up a loop to fetch data periodically. This is useful for data collection, monitoring changes in web content, or tracking real-time data from APIs.

5. Web testing and automation:

Requests can be used for testing web applications by simulating various HTTP requests and verifying the responses. The Requests library enables you to automate web tasks such as logging into websites, submitting forms, or interacting with APIs. You can send the necessary HTTP requests, handle the responses, and perform further actions based on the results. This helps in streamlining testing processes, automating repetitive tasks, and interacting with web services programmatically.

6. Authentication and session management:

Requests provides built-in support for handling different types of authentication mechanisms, including Basic Auth, OAuth, and JWT, allowing you to authenticate and manage sessions when interacting with web services or APIs. This allows you to interact securely with web services and APIs that require authentication for accessing protected resources.

7. Proxy and SSL handling

Requests provides built-in support for working with proxies, enabling you to route your requests through different IP addresses, by passing the ‘proxies’ parameter with the proxy dictionary to the request method, you can route the request through the specified proxy, if your proxy requires authentication, you can include the username and password in the proxy URL. It also handles SSL/TLS certificates and allows you to verify or ignore SSL certificates during HTTPS requests, this flexibility enables you to work with different network configurations and ensure secure communication while interacting with web services and APIs.

8. Microservices and serverless architecture

In microservices or serverless architectures, where components communicate over HTTP, the Requests library can be used to make requests between different services, establish communication between different services, retrieve data from other endpoints, or trigger actions in external services. This allows for seamless integration and collaboration between components in a distributed architecture, enabling efficient data exchange and service orchestration.

Best practices for using the Requests library

Here are some of the practices that are needed to be followed to make good use of Requests Library.

1. Use session objects

Session object persists parameters and cookies across multiple requests being made. It allows connection pooling which means that instead of creating a new connection every time you make a request, it holds onto the existing connection and saves time. In this way, it helps to gain significant performance improvements.

2. Handle errors and exceptions

It is important to handle errors and exceptions while making requests. The errors can include problems with the network, issues on the server, or receiving unexpected or invalid responses. You can handle these errors using try-except block and the exception classes in the Requests library.

By using try-except block, you can anticipate potential errors and instruct the program on how to handle them. In case of built-in exception classes you can catch specific exceptions and handle them accordingly. For example, you can catch a network-related error using the requests.exceptions.RequestException class, or handle server errors with the requests.exceptions.HTTPError class.

3. Configure headers and authentication

The Requests library offers powerful features for configuring headers and handling authentication during HTTP requests. HTTP headers serve an important purpose in communicating specific instructions and information between a client (such as a web browser or an API consumer) and a server. These headers are particularly useful for tailoring the server’s response according to the client’s needs.

One common use case for HTTP headers is to specify the desired format of the response. By including an appropriate header, you can indicate to the server the preferred format, such as JSON or XML, in which you would like to receive the data. This allows the server to tailor the response accordingly, ensuring compatibility with your application or system.

Headers are also instrumental in providing authentication credentials. The Requests library supports various authentication methods, such as Basic Auth, OAuth, or using API keys.
It is crucial to ensure that you include necessary headers and provide the required authentication credentials while interacting with web services, it helps you to establish secure and successful communication with the server.

4. Leverage response handling

The Response object that is received after making a request using Requests library, you need to handle and process the response data effectively. There are various methods to access and extract the required information from the response.
For example, parsing JSON data, accessing headers, and handling binary data.

5. Utilize timeout

When making requests to a remote server using methods like ‘requests.get’ or ‘requests.put’, it is important to consider potential for long response times or connectivity issues. Without a timeout parameter, these requests may hang for an extended period, which can be problematic for backend systems that require prompt data processing and responses.
For this purpose, it is recommended to set a timeout when making the HTTP requests using the timeout parameter, it helps to prevent the code from hanging indefinitely and raise the TimeoutException indicating that request has taken longer tie than the specified timeout period.

Overall, the requests library provides a powerful and flexible API for interacting with web services and APIs, making it a crucial tool for any Python developer working with web data.

Wrapping up

As we wrap up this blog, it is clear that the Requests library is an invaluable tool for any developer working with HTTP-based applications. Its ease of use, flexibility, and extensive functionality makes it an essential component in any developer’s toolkit

Whether you’re building a simple web scraper or a complex API client, Requests provides a robust and reliable foundation on which to build your application. Its practical usefulness cannot be overstated, and its widespread adoption within the developer community is a testament to its power and flexibility.

In summary, the Requests library is an essential tool for any developer working with HTTP-based applications. Its intuitive API, extensive functionality, and robust error handling make it a go-to choice for developers around the world.

The digital age has resulted in the generation of enormous amounts of data daily, ranging from social media interactions to online shopping habits. It is estimated that every day, 2.5 quintillion bytes of data are created. Although this may seem daunting, it provides an opportunity to gain valuable insights into consumer behavior, patterns, and trends.

This is where data science plays a crucial role. In this article, we will delve into the fascinating realm of Data Science and examine why it is fast becoming one of the most in-demand professions. 

What is data science? 

Data Science is a field that encompasses various disciplines, including statistics, machine learning, and data analysis techniques to extract valuable insights and knowledge from data. The primary aim is to make sense of the vast amounts of data generated daily by combining statistical analysis, programming, and data visualization.

It is divided into three primary areas: data preparation, data modeling, and data visualization. Data preparation entails organizing and cleaning the data, while data modeling involves creating predictive models using algorithms. Finally, data visualization involves presenting data in a way that is easily understandable and interpretable. 

Importance of data science 

The application is not limited to just one industry or field. It can be applied in a wide range of areas, from finance and marketing to sports and entertainment. For example, in the finance industry, it is used to develop investment strategies and detect fraudulent transactions. In marketing, it is used to identify target audiences and personalize marketing campaigns. In sports, it is used to analyze player performance and develop game strategies.

It is a critical field that plays a significant role in unlocking the power of big data in today’s digital age. With the vast amount of data being generated every day, companies and organizations that utilize data science techniques to extract insights and knowledge from data are more likely to succeed and gain a competitive advantage. 

Skills required for data science 

It is a multi-faceted field that necessitates a range of competencies in statistics, programming, and data visualization.

Proficiency in statistical analysis is essential for Data Scientists to detect patterns and trends in data. Additionally, expertise in programming languages like Python or R is required to handle large data sets. Data Scientists must also have the ability to present data in an easily understandable format through data visualization.

A sound understanding of machine learning algorithms is also crucial for developing predictive models. Effective communication skills are equally important for Data Scientists to convey their findings to non-technical stakeholders clearly and concisely.

Conclusion 

The significance cannot be overstated, as it has the potential to bring about substantial changes in the way organizations operate and make decisions. However, this field demands a distinct blend of competencies, such as expertise in statistics, programming, and data visualization 

SQL (Structured Query Language) is an important tool for data scientists. It is a programming language used to manipulate data stored in relational databases. Mastering SQL concepts allows a data scientist to quickly analyze large amounts of data and make decisions based on their findings. Here are some essential SQL concepts that every data scientist should know:

First, understanding the syntax of SQL statements is essential in order to retrieve, modify or delete information from databases. For example, statements like SELECT and WHERE can be used to identify specific columns and rows within the database that need attention. A good knowledge of these commands can help a data scientist perform complex operations with ease.

Second, developing an understanding of database relationships such as one-to-one or many-to-many is also important for a data scientist working with SQL.

Here’s an interesting read about Top 10 SQL commands

Let’s dive into some of the key SQL concepts that are important to learn for a data scientist.  

1. Formatting Strings

We are all aware that cleaning up the raw data is necessary to improve productivity overall and produce high-quality decisions. In this case, string formatting is crucial and entails editing the strings to remove superfluous information. For transforming and manipulating strings, SQL provides a large variety of string methods. When combining two or more strings, CONCAT is utilized. The user-defined values that are frequently required in data science can be substituted for the null values using COALESCE. Tiffany Payne  

2. Stored Methods

We can save several SQL statements in our database for later use thanks to stored procedures. When invoked, it allows for reusability and has the ability to accept argument values. It improves performance and makes modifications simpler to implement. For instance, we’re attempting to identify all A-graded students with majors in data science. Keep in mind that CREATE PROCEDURE must be invoked using EXEC in order to be executed, exactly like the function definition. Paul Somerville 

3. Joins

Based on the logical relationship between the tables, SQL joins are used to merge the rows from various tables. In an inner join, only the rows from both tables that satisfy the specified criteria are displayed. In terms of vocabulary, it can be described as an intersection. The list of pupils who have signed up for sports is returned. Sports ID and Student registration ID are identical, please take note. Left Join returns every record from the LEFT table, while Right Join only shows the matching entries from the RIGHT table. Hamza Usmani 

4. Subqueries

Knowing how to utilize subqueries is crucial for data scientists because they frequently work with several tables and can use the results of one query to further limit the data in the primary query. The nested or inner query is another name for it. The subquery is conducted before the main query and needs to be surrounded in parenthesis. It is referred to as a multi-line subquery and requires the use of multi-line operators if it returns more than one row. Tiffany Payne 

5. Left Joins vs Inner Joins

It’s easy to confuse left joins and inner joins, especially for those who are still getting their feet wet with SQL or haven’t touched the language in a while. Make sure that you have a complete understanding of how the various joins produce unique outputs. You will likely be asked to do some kind of join in a significant number of interview questions, and in certain instances, the difference between a correct response and an incorrect one will depend on which option you pick. Tom Miller 

6. Manipulation of dates and times

There will most likely be some kind of SQL query using date-time data, and you should prepare for it. For instance, one of your tasks can be to organize the data into groups according to the months or to change the format of a variable from DD-MM-YYYY to only the month. You should be familiar with the following functions:

– EXTRACT
– DATEDIFF
– DATE ADD, DATE SUB
– DATE TRUNC 

Olivia Tonks 

7. Procedural Data Storage 

Using stored procedures, we can compile a series of SQL commands into a single object in the database and call it whenever we need it. It allows for reusability and when invoked, can take in values for its parameters. It improves efficiency and makes it simple to implement new features. Using this method, we can identify the students with the highest GPAs who have declared a particular major. One goal is to identify all A-students whose major is Data Science. It’s important to remember that, like a function declaration, calling a CREATE PROCEDURE with EXEC is necessary for the procedure to be executed. Nely Mihaylova 

8. Connecting SQL to Python or R 

A developer who is fluent in a statistical language, like Python or R, may quickly and easily use the packages of
language to construct machine learning models on a massive dataset stored in a relational database management system. A programmer’s employment prospects will improve dramatically if they are fluent in both these statistical languages and SQL. Data analysis, dataset preparation, interactive visualizations, and more may all be accomplished in SQL Server with the help of Python or R. Rene Delgado  

9. Features of windows

In order to apply aggregate and ranking functions over a specific window, window functions are used (set of rows). When defining a window with a function, the OVER clause is utilized. The OVER clause serves dual purposes:

– Separates rows into groups (PARTITION BY clause is used).
– Sorts the rows inside those partitions into a specified order (ORDER BY clause is used).
– Aggregate window functions refer to the application of aggregate
functions like SUM(), COUNT(), AVERAGE(), MAX(), and MIN() over a specific window (set of rows). Tom Hamilton Stubber  

10. The emergence of Quantum ML

With the use of quantum computing, more advanced artificial intelligence and machine learning models might be created. Despite the fact that true quantum computing is still a long way off, things are starting to shift as a result of the cloud-based quantum computing tools and simulations provided by Microsoft, Amazon, and IBM. Combining ML and quantum computing has the potential to greatly benefit enterprises by enabling them to take on problems that are currently insurmountable. Steve Pogson 

11. Predicates

Predicates occur from your WHERE, HAVING, and JOIN clauses. They limit the amount of data that has to be processed to run your query. If you say SELECT DISTINCT customer_name FROM customers WHERE signup_date = TODAY() that’s probably a much smaller query than if you run it without the WHERE clause because, without it, we’re selecting every customer that ever signed up!

Data science sometimes involves some big datasets. Without good predicates, your queries will take forever and cost a ton on the infra bill! Different data warehouses are designed differently, and data architects and engineers make different decisions about to lay out the data for the best performance. Knowing the basics of your data warehouse, and how the tables you’re using are laid out, will help you write good predicates that save your company a lot of money during the year, and just as importantly, make your queries run much faster.

For example, a query that runs quickly but simply touches a huge amount of data in Bigquery can be really expensive if you’re using on-demand pricing which scales with the amount of data touched by the query. The same query can be really cheap if you’re using Bigquery’s Flat-rate pricing or Snowflake, both of which are affected by how long your query takes to run, not how much data is fed into it. Kyle Kirwan 

12. Query Syntax

This is what makes SQL so powerful and much easier than coding individual statements for every task we want to complete when extracting data from a database. Every query starts with one or more clauses such as SELECT, FROM, or WHERE – each clause gives us different capabilities; SELECT allows us to define which columns we’d like returned in the results set; FROM indicates which table name(s) we should get our data from; WHERE allows us to specify conditions that rows must meet for them to be included in our result set etcetera! Understanding how all these clauses work together will help you write more effective and efficient queries quickly, allowing you to do better analysis faster! John Smith 

Elevate your business with essential SQL concepts 

AI and machine learning, which have been rapidly emerging, are quickly becoming one of the top trends in technology. Developments in AI and machine learning are being seen all over the world, from big businesses to small startups.

Businesses utilizing these two technologies are able to create smarter systems for their customers and employees, allowing them to make better decisions faster.

These advancements in artificial intelligence and machine learning are helping companies reach new heights with their products or services by providing them with more data to help inform decision-making processes.

Additionally, AI and machine learning can be used to automate mundane tasks that take up valuable time. This could mean more efficient customer service or even automated marketing campaigns that drive sales growth through
real-time analysis of consumer behavior. Rajesh Namase

Wrapping up

In conclusion, Python has become the go-to programming language in the data science community due to its simplicity, flexibility, and extensive range of libraries and tools.

In this blog post, the author introduces the new blog series about the titular three main disciplines or knowledge domains of software development, project management, and data science. Amidst the mercurial evolving global digital economy, how can job-seekers harness the lucrative value of those fields–esp. data science, vis-a-vis improving their employability?

 

Introduction/Overview:

To help us launch this blog series, I will gladly divulge two embarrassing truths. These are: 

1. Despite my marked love of LinkedIn, and despite my decent / above-average levels of general knowledge, I cannot keep up with the ever-changing statistics or news reports vis-a-vis whether–at any given time, the global economy is favorable to job-seekers, or to employers, or is at equilibrium for all parties–i.e., governments, employers, and workers.
2. Despite having rightfully earned those fancy three letters after my name, as well as a post-graduate certificate from the U. New Mexico & DS-Dojo, I (used to think I) hate math, or I (used to think I) cannot learn math; not even if my life depended on it!

 

Background:

Following my undergraduate years of college algebra and basic discrete math–and despite my hatred of mathematics since 2nd grade (chief culprit: multiplication tables!), I had fallen in love (head-over-heels indeed!) with the interdisciplinary field of research methods. And sure, I had lucked out in my Masters (of Arts in Communication Studies) program, as I only had to take the qualitative methods course.

 

 

But our instructor couldn’t really teach us about interpretive methods, ethnography, and qualitative interviewing etc., without at least “touching” on quantitative interviewing/surveys, quantitative data-analysis–e.g. via word counts, content-analysis, etc.

Fast-forward; year: 2012. Place: Drexel University–in Philadelphia, for my Ph.D. program (in Communication, Culture, and Media). This time, I had to face the dreaded mathematics/statistics monster. And I did, but grudgingly.

Let’s just get this over with, I naively thought; after all, besides passing this pesky required pre-qualifying exam course, who needs stats?!

 

About software development:

Fast-forward again; year: 2020. Place(s): Union, NJ and Wenzhou, Zhejiang Province; Hays, KS; and Philadelphia all over again. Five years after earning the Ph.D., I had to reckon with an unfair job loss, and chaotic seesaw-moves between China and the USA, and Philadelphia and Kansas, etc. 

Thus, one thing led to another, and soon enough, I was practicing algorithms and data-structures, learning about the basic “trouble-trio” of web-development–i.e., HTML, CSS, and JavaScript, etc.! 

 

Read more about Programming Languages

 

But like many other folks who try this route, I soon came face-to-face with that oh-so-debilitative monster: self-doubt! No way, I thought. I’m NOT cut out to be a software-engineer! I thus dropped out of the bootcamp I had enrolled in and continued my search for a suitable “plan-B” career.

 

About project management:

Eventually (around mid/late-2021), I discovered the interdisciplinary field of project management. Simply defined (e.g. by Te Wu, 2020; link), project management is

“A time-limited, purpose-driven, and often unique endeavor to create an outcome, service, product, or deliverable.”

One can also break down the constituent conceptual parts of the field (e.g. as defined by Belinda Goodrich, 2021; link) as: 

• Project life cycle, 
• Integration, 
• Scope, 
• Schedule, 
• Cost, 
• Quality, 
• Resources, 
• Communications, 
• Risk, 
• Procurement, 
• Stakeholders, and 
• Professional responsibility / ethics. 

 

Ah…yes! I had found my sweet spot, indeed. or, so I thought. 

 

Hard truths:

Eventually, I experienced a series of events that can be termed “slow-motion epiphanies” and hard truths. Among many, below are three prime examples.

 

Hard Truth 1: The quantifiability of life:

For instance, among other “random” models: one can generally presume–with about 95% certainty (ahem!)–that most of the phenomena we experience in life can be categorized under three broad classes:

 

1. Phenomena we can easily describe and order, using names (nominal variables);
2. Phenomena we can easily group or measure in discrete and evenly-spaced amounts (ordinal variables);
3. And phenomena that we can measure more accurately, and which: i)–is characterized by trait number two above, and ii)–has a true 0 (e.g., Wrench et Al; link).

 

Hard Truth 2: The probabilistic essence of life:

Regardless of our spiritual beliefs, or whether or not we hate math/science, etc., we can safely presume that the universe we live in is more or less a result of probabilistic processes (e.g., Feynman, 2013). 

 

Hard truth 3: What was that? “Show you the money (!),” you demanded? Sure! But first, show me your quantitative literacy, and critical-thinking skills!

And finally, related to both the above realizations: while it is true indeed that there are no guarantees in life, we can nonetheless safely presume that professionals can improve their marketability by demonstrating their critical-thinking-, as well as quantitative literacy skills.

 

Bottomline; The value of data science:

Overall, the above three hard truths are prototypical examples of the underlying rationale(s) for this blog series. Each week, DS-Dojo will present our readers with some “food for thought” vis-a-vis how to harness the priceless value of data science and various other software-development and project-management skills / (sub-)topics. 

 

No, dear reader; please do not be fooled by that “OmG, AI is replacing us (!)” fallacy. Regardless of how “awesome” all these new fancy AI tools are, the human touch is indispensable!

In this blog, we will discuss exploratory data analysis, also known as EDA, and why it is important. We will also be sharing code snippets so you can try out different analysis techniques yourself. So, without any further ado let’s dive right in. 

What is Exploratory Data Analysis (EDA)? 

“The greatest value of a picture is when it forces us to notice what we never expected to see.”  John Tukey, American Mathematician 

A core skill to possess for someone who aims to pursue data science, data analysis or affiliated fields as a career is exploratory data analysis (EDA). To put it simply, the goal of EDA is to discover underlying patterns, structures, and trends in the datasets and drive meaningful insights from them that would help in driving important business decisions. 

The data analysis process enables analysts to gain insights into the data that can inform further analysis, modeling, and hypothesis testing.  

EDA is an iterative process of conglomerative activities which include data cleaning, manipulation and visualization. These activities together help in generating hypotheses, identifying potential data cleaning issues, and informing the choice of models or modeling techniques for further analysis. The results of EDA can be used to improve the quality of the data, to gain a deeper understanding of the data, and to make informed decisions about which techniques or models to use for the next steps in the data analysis process. 

Often it is assumed that EDA is to be performed only at the start of the data analysis process, however the reality is in contrast to this popular misconception, as stated EDA is an iterative process and can be revisited numerous times throughout the analysis life cycle if need may arise.  

In this blog while highlighting the importance and different renowned techniques of EDA we will also show you examples with code so you can try them out yourselves and better comprehend what this interesting skill is all about.

Importance of EDA: 

One of the key advantages of EDA is that it allows you to develop a deeper understanding of your data before you begin modelling or building more formal, inferential models. This can help you identify  

• Important variables,  
• Understand the relationships between variables, and  
• Identify potential issues with the data, such as missing values, outliers, or other problems that might affect the accuracy of your models. 

Another advantage of EDA is that it helps in generating new insights which may incur associated hypotheses, those hypotheses then can be tested and explored to gain a better understanding of the dataset. 

Finally, EDA helps you uncover hidden patterns in a dataset that were not comprehensible to the naked eye, these patterns often lead to interesting factors that one couldn’t even think would affect the target variable. 

Want to start your EDA journey, well you can always get yourself registered at Data Science Bootcamp.  

Common EDA techniques: 

The technique you employ for EDA is intertwined with the task at hand, many times you would not require implementing all the techniques, on the other hand there would be times that you’ll need accumulation of the techniques to gain valuable insights. To familiarize you with a few we have listed some of the popular techniques that would help you in EDA. 

Visualization:  

One of the most popular and effective ways to explore data is through visualization. Some popular types of visualizations include histograms, pie charts, scatter plots, box plots and much more. These can help you understand the distribution of your data, identify patterns, and detect outliers. 

Below are a few examples on how you can use visualization aspect of EDA to your advantage: 

Histogram: 

The histogram is a kind of visualization that shows the frequencies of each category in a dataset. 

The above graph shows us the number of responses belonging to different age groups and they have been partitioned based on how many came to the appointment and how many did not show up. 

Pie Chart: 

A pie chart is a circular image, it is usually used for a single feature to indicate how the data of that feature are distributed, commonly represented in percentages. 

 

The pie chart shows the distribution that 20.2% of the total data comprises of individuals who did not show up for the appointment while 79.8% of individuals did show up. 

Box Plot: 

Box plot is also an important kind of visualization that is used to check how the data is distributed, it shows the five number summary of the dataset, which is quite useful in many aspects such as checking if the data is skewed, or detecting the outliers etc.  

 

The box plot shows the distribution of the Age column, segregated on the basis of individuals who showed and did not show up for the appointments. 

Descriptive statistics:  

Descriptive statistics are a set of tools for summarizing data in a way that is easy to understand. Some common descriptive statistics include mean, median, mode, standard deviation, and quartiles. These can provide a quick overview of the data and can help identify the central tendency and spread of the data.

 

Grouping and aggregating:  

One way to explore a dataset is by grouping the data by one or more variables, and then aggregating the data by calculating summary statistics. This can be useful for identifying patterns and trends in the data. 

 

Data cleaning:  

Exploratory data analysis also includes cleaning data, it may be necessary to handle missing values, outliers, or other data issues before proceeding with further analysis.  

 

As you can see, fortunately this dataset did not have any missing value. 

Correlation analysis: 

Correlation analysis is a technique for understanding the relationship between two or more variables. You can use correlation analysis to determine the degree of association between variables, and whether the relationship is positive or negative. 

The heatmap indicates to what extent different features are correlated to each other, with 1 being highly correlated and 0 being no correlation at all. 

Types of EDA: 

There are a few different types of exploratory data analysis (EDA) that are commonly used, depending on the nature of the data and the goals of the analysis. Here are a few examples: 

Univariate EDA:  

Univariate EDA, short for univariate exploratory data analysis, examines the properties of a single variable by techniques such as histograms, statistics of central tendency and dispersion, and outliers detection. This approach helps understand the basic features of the variable and uncover patterns or trends in the data. 

 

The pie chart indicates what percentage of individuals from the total data are identified as alcoholic. 

Bivariate EDA:  

This type of EDA is used to analyse the relationship between two variables. It includes techniques such as creating scatter plots and calculating correlation coefficients and can help you understand how two variables are related to each other.

 

The bar chart shows what percentage of individuals are alcoholic or not and whether they showed up for the appointment or not. 

Multivariate EDA:  

This type of EDA is used to analyze the relationships between three or more variables. It can include techniques such as creating multivariate plots, running factor analysis, or using dimensionality reduction techniques such as PCA to identify patterns and structure in the data.

The above visualization is distplot of kind, bar, it shows what percentage of individuals belong to one of the possible four combinations diabetes and hypertension, moreover they are segregated on the basis of gender and whether they showed up for appointment or not.  

Time-series EDA:  

This type of EDA is used to understand patterns and trends in data that are collected over time, such as stock prices or weather patterns. It may include techniques such as line plots, decomposition, and forecasting. 

 

This kind of chart helps us gain insight of the time when most appointments were scheduled to happen, as you can see around 80k appointments were made for the month of May.

Spatial EDA:  

This type of EDA deals with data that have a geographic component, such as data from GPS or satellite imagery. It can include techniques such as creating choropleth maps, density maps, and heat maps to visualize patterns and relationships in the data.

 

In the above map, the size of the bubble indicates the number of appointments booked in a particular neighborhood while the hue indicates the percentage of individuals who did not show up for the appointment.  

Popular libraries for EDA: 

Following is a list of popular libraries that python has to offer which you can use for Exploratory Data Analysis.   

1. Pandas: This library offers efficient, adaptable, and clear data structures meant to simplify handling “relational” or “labelled” data. It is a useful tool for manipulating and organizing data. 
2. NumPy: This library provides functionality for handling large, multi-dimensional arrays and matrices of numerical data. It also offers a comprehensive set of high-level mathematical operations that can be applied to these arrays. It is a dependency for various other libraries, including Pandas, and is considered a foundational package for scientific computing using Python. 
3. Matplotlib: Matplotlib is a Python library used for creating plots and visualizations, utilizing NumPy. It offers an object-oriented interface for integrating plots into applications using various GUI toolkits such as Tkinter, wxPython, Qt, and GTK. It has a diverse range of options for creating static, animated, and interactive plots. 
4. Seaborn: This library is built on top of Matplotlib and provides a high-level interface for drawing statistical graphics. It’s designed to make it easy to create beautiful and informative visualizations, with a focus on making it easy to understand complex datasets. 
5. Plotly: This library is a data visualization tool that creates interactive, web-based plots. It works well with the pandas library and it’s easy to create interactive plots with zoom, hover, and other features. 
6. Altair: is a declarative statistical visualization library for Python. It allows you to quickly and easily create statistical graphics in a simple, human-readable format.

It helps in generating new insights, identifying potential issues and informing the choice of models or techniques for further analysis.

It is an iterative process that can be revisited throughout the data analysis life cycle. Overall, EDA is an important skill that can inform important business decisions and generate valuable insights from data. 

 

Bellevue, Washington (January 11, 2023) – The following statement was released today by Data Science Dojo, through its Marketing Manager Nathan Piccini, in response to questions about future in-person bootcamps: 

“They’re back.”

In this blog, we will explore some of the difficulties you may face while animating data science and machine learning videos in Adobe After Effects and how to overcome them. 

(more…)

Data science myths are one of the main obstacles preventing newcomers from joining the field. In this blog, we bust some of the biggest myths shrouding the field. 

 

The US Bureau of Labor Statistics predicts that data science jobs will grow up to 36% by 2031. There’s a clear market need for the field and its popularity only increases by the day. Despite the overwhelming interest data science has generated, there are many myths preventing new entry into the field.  

 

 

Data science myths, at their heart, follow misconceptions about the field at large. So, let’s dive into unveiling these myths. 

 

1. All data roles are identical 

 It’s a common data science myth that all data roles are the same. So, let’s distinguish between some common data roles – data engineer, data scientist, and data analyst. A data engineer focuses on implementing infrastructure for data acquisition and data transformation to ensure data availability to other roles. 

A data analyst, however, uses data to report any observed trends and patterns to report. Using both the data and the analysis provided by a data engineer and a data analyst, a data scientist works on predictive modeling, distinguishing signals from noise, and deciphering causation from correlation.  

Finally, these are not the only data roles. Other specialized roles such as data architects and business analysts also exist in the field. Hence, a variety of roles exist under the umbrella of data science, catering to a variety of individual skill sets and market needs. 

 

2. Graduate studies are essential 

 Another myth preventing entry into the data science field is that you need a master’s or Ph.D. degree. This is also completely untrue.  

In busting the last myth, we saw how data science is a diverse field welcoming various backgrounds and skill sets. As such, a Ph.D. or master’s degree is only valuable for specific data science roles. For instance, higher education is useful in pursuing research in data science.  

However, if you’re interested in working on real-life complex data problems using data analytics methods such as deep learning, only knowledge of those methods is necessary. And so, rather than a master’s or Ph.D. degree, acquiring specific valuable skills can come in handier in kickstarting your data science career.  

 

3. Data scientists will be replaced by artificial intelligence   

As artificial intelligence advances, a common misconception arises that AI will replace all human intelligent labor. This misconception has also found its way into data science forming one of the most popular myths that AI will replace data scientists.  

This is far from the truth because. Today’s AI systems, even the most advanced ones, require human guidance to work. Moreover, the results produced by them are only useful when analyzed and interpreted in the context of real-world phenomena, which requires human input. 

So, even as data science methods head towards automation, it’s data scientists who shape the research questions, devise the analytic procedures to be followed, and lastly, interpret the results.

4. Data scientists are expert coders 

 Being a data scientist does not translate into being an expert programmer! Programming tasks are only one component of the data science field, and these too, vary from one data science subfield to another.  

For example, a business analyst would require a strong understanding of business, and familiarity with visualization tools, while minimal coding knowledge would suffice. At the same time, a machine learning engineer would require extensive knowledge of Python.  

In conclusion, the extent of programming knowledge depends on where you want to work across the broad spectrum of the data science field.  

 

5. Learning a tool is enough to become a data scientist  

Knowing a particular programming language, or a data visualization tool is not all you need to become a data scientist. While familiarity with tools and programming languages certainly helps, this is not the foundation of what makes a data scientist. 

So, what makes a good data science profile? That, really, is a combination of various skills, both technical and non-technical. On the technical end, there are mathematical concepts, algorithms, data structures, etc. While on the non-technical end there are business skills and understanding of various stakeholders in a particular situation.  

To conclude, a tool can be an excellent way to implement data science skills. However, it isn’t what will teach you the foundations or the problem-solving aspect of data science. 

 

6. Data scientists only work on predictive modeling 

Another myth! Very few people would know that data scientists spend nearly 80% of their time on data cleaning and transforming before working on data modeling. In fact, bad data is the major cause of productivity levels not being up to par in data science companies. This requires significant focus on producing good quality data in the first place. 

This is especially true when data scientists work on problems involving big data. These problems involve multiple steps of which data cleaning and transformations are key. Similarly, data from multiple sources and raw data can contain junk that needs to be carefully removed so that the model runs smoothly.   

So, unless we find a quick-fix solution to data cleaning and transformation, it’s a total myth that data scientists only work on predictive modeling.  

 

7. Transitioning to data science is impossible 

Data science is a diverse and versatile field welcoming a multitude of background skill sets. While technical knowledge of algorithms, probability, calculus, and machine learning can be great, non-technical knowledge such as business skills or social sciences can also be useful for a data science career. 

 At its heart, data science involves complex problem solving involving multiple stakeholders. For a data-driven company, a data scientist from a purely technical background could be valuable but so could one from a business background who can better interpret results or shape research questions. 

 And so, it’s a total myth that transitioning to data science from another field is impossible.

“The more I learn, the more I realize what I don’t know”

(A quote by Raja Iqbal, CEO of DS-Dojo)

In our current era, the terms “AI”, “ML”, “analytics”–etc., are indeed THE “buzzwords” du jour. And yes, these interdisciplinary subjects/topics are **very** important, given our ever-increasing computing capabilities, big-data systems, etc. 

The problem, however, is that **very few** folks know how to teach these concepts! But to be fair, teaching in general–even for the easiest subjects–is hard. In any case, **this**–the ability to effectively teach the concepts of data-science–is the genius of DS-Dojo. Raja and his team make these concepts considerably easy to grasp and practice, giving students both a “big picture-,” as well as a minutiae-level understanding of many of the necessary details. 

Learn more about the Data Science Bootcamp course offered by Data Science Dojo

Still, a leery prospective student might wonder if the program is worth their time, effort, and financial resources. In the sections below, I attempt to address this concern, elaborating on some of the unique value propositions of DS-Dojo’s pedagogical methods.

The More Things Change…

Data Science enthusiasts today might not realize it, but many of the techniques–in their basic or other forms–have been around for decades. Thus, before diving into the details of data-science processes, students are reminded that long before the terms “big data,” AI/ML and others became popularized, various industries had all utilized techniques similar to many of today’s data-science models. These include (among others): insurance, search-engines, online shopping portals, and social networks. 

This exposure helps Data-Science Dojo students consider the numerous creative ways of gathering and using big-data from various sources–i.e. directly from human activities or information, or from digital footprints or byproducts of our use of online technologies.

 

The big picture of the Data Science Bootcamp

As for the main curriculum contents, first, DS-Dojo students learn the basics of data exploration, processing/cleaning, and engineering. Students are also taught how to tell stories with data. After all, without predictive or prescriptive–and other–insights, big data is useless.

The bootcamp also stresses the importance of domain knowledge, and relatedly, an awareness of what precise data-points should be sought and analyzed. DS-Dojo also trains students to critically assess: why, and how should we classify data? Students also learn the typical data-collection, processing, and analysis pipeline, i.e.:

1. Influx
2. Collection
3. Preprocessing
4. Transformation
5. Data-mining
6. And finally, interpretation and evaluation.

However, any aspiring (good) data scientist should disabuse themselves of the notion that the process doesn’t present challenges. Au contraire, there are numerous challenges; e.g. (among others):

1. Scalability
2. Dimensionality
3. Complex and heterogeneous data
4. Data quality
5. Data ownership and distribution, 
6. Privacy, 
7. Reaction time.

 

Deep dives

Following the above coverage of the craft’s introductory processes and challenges, DS-Dojo students are then led earnestly into the deeper ends of data-science characteristics and features. For instance, vis-a-vis predictive analytics, how should a data-scientist decide when to use unsupervised learning, versus supervised learning? Among other considerations, practitioners can decide using the criteria listed below.

 

Unsupervised Learning…Vs. … >>	<< …Vs. …Supervised Learning
>> Target values unknown	>> Targets known
>> Training data unlabeled	>> Data labeled
>> Goal: discover information hidden in the data	>> Goal: Find a way to map attributes to target value(s)
>> Clustering	>> Classification and regression

 

Read more about the supervised and unsupervised learning

 

Overall, the main domains covered by DS-Dojo’s data-science bootcamp curriculum are:

• An introduction/overview of the field, including the above-described “big picture,” as well as visualization, and an emphasis on story-telling–or, stated differently, the retrieval of actual/real insights from data;
• Overview of classification processes and tools
•  Applications of classification
• Unsupervised learning; 
• Regression;
• Special topics–e.g., text-analysis
• And “last but [certainly] not least,” big-data engineering and distribution systems. 

 

Method-/Tool-Abstraction

In addition to the above-described advantageous traits, data-science enthusiasts, aspirants, and practitioners who join this program will be pleasantly surprised with the bootcamp’s de-emphasis on specific tools/approaches.  In other words, instead of using doctrinaire approaches that favor only Python, or R, Azure, etc., DS-Dojo emphasizes the need for pragmatism; practitioners should embrace the variety of tools at our disposal.

“Whoo-Hoo! Yes, I’m a Data Scientist!”

By the end of the bootcamp, students might be tempted to adopt the above stance–i.e., as stated above (as this section’s title/subheading). But as a proud alumnus of the program, I would cautiously respond: “Maybe!” And if you have indeed mastered the concepts and tools, congratulations!

But strive to remember that the most passionate data-science practitioners possess a rather paradoxical trait: humility, and an openness to lifelong learning. As Raja Iqbal, CEO of DS-Dojo pointed out in one of the earlier lectures: The more I learn, the more I realize what I don’t know. Happy data-crunching!

Every eCommerce business depends on information to improve its sales. Data science can source, organize and visualize information. It also helps draw insights about customers, marketing channels, and competitors.

 

Every piece of information can serve different purposes. You can use data science to improve sales, customer service, user experience, marketing campaigns, purchase journeys, and more.

 

How to use Data Science to boost eCommerce sales

Sales in eCommerce depend on a variety of factors. You can use data to optimize each step in a customer’s journey to gain conversions and enhance revenue from each conversion.

Analyze Consumer Behavior

Data science can help you learn a lot about the consumer. Understanding consumer behavior is crucial for eCommerce businesses as it dictates the majority of their decisions.

 

Consumer behavior analysis is all about understanding the relationship between things you can do and customers’ reactions to them. This analysis requires data science as well as psychology. The end goal is not just understanding consumer behavior, but predicting it.

 

For example, if you have an eCommerce store for antique jewelry, you will want to understand what type of people buy antique jewelry, where they search for it, how they buy it, what information they seek before purchasing, what occasions they buy it for, and so on.

 

 

 

You can extract data on consumer behavior on your website, social media, search engines, and even other eCommerce websites. This data will help you understand customers and predict their behavior. This is crucial for audience segmentation.

 

Data science can help segment audiences based on demographics, characteristics, preferences, shopping patterns, spending habits, and more. You create different strategies to convert audiences of different segments.

 

Audience segments play a crucial role in designing purchase journeys, starting from awareness campaigns all the way to purchase and beyond.

 

Optimize digital marketing for better conversion

You need insights from data analytics to make important marketing decisions. Customer acquisition information can tell you where the majority of your audience comes from. You can also identify which sources give you maximum conversions.

 

You can then use data to improve the performance of your weak sources and reinforce the marketing efforts of high-performing sources. Either way, you can ensure that your marketing efforts are helping your bottom line.

 

Once you have locked down your channels of marketing, data science can help you improve results from marketing campaigns. You can learn what type of content or ads perform the best for your eCommerce website.

 

Data science will also tell you when the majority of your audience is online on the channel and how they interact with your content. Most marketers try to fight the algorithms to win. But with data science, you can uncover the secrets of social media algorithms to maximize your conversions.

 

Suggest products for upselling & cross-selling

Upselling & Cross-selling are some of the most common sales techniques employed by ecommerce platforms. Data science can help make them more effective. With Market Basket or Affinity Analysis, data scientists can identify relationships between different products. 

 

By analyzing such information of past purchases and shopping patterns you can derive criteria for upselling and cross-selling. The average amount they spend on a particular type of product tells you how high you can upsell. If the data says that customers are more likely to purchase a particular brand, design, or color; you can upsell accordingly. 

 

 

 

Similarly, you can offer relevant cross-selling suggestions based on customers’ data. Each product opens numerous cross-selling options.

 

Instead of offering general options, you can use data from various sources to offer targeted suggestions. You can give suggestions based on individual customers’ preferences. For instance, A customer is more likely to click on a suggestion saying “A Red Sweater to go with your Blue Jeans’ ‘ if their previous purchase shows an inclination for the color red.

 

This way data science can help increase probability of upsold & cross-sold purchases so that eCommerce businesses get more revenue from their customers.

Analyze consumer feedback

Consumers provide feedback in a variety of ways, some of which can only be understood by learning data science. It is not just about reviews and ratings. Customers speak about their experience through social media posts, social shares, and comments as well.

Feedback data can be extracted from several places and usually comes in large volumes. Data scientists use techniques like text analytics, computational linguistics, and natural language processing to analyze this data.

 

For instance, you can compare the percentage of positive words and negative words used in reviews to get a general idea about customer satisfaction.

 

But feedback analysis does not stop with language. Consumer feedback is also hidden in metrics like time spent on page, CTR, cart abandonment, clicks on page, heat maps and so on. Data on such sublime behaviors can tell you more about the customer’s experience with your eCommerce website than reviews, ratings and feedback forms.

 

This information helps you identify problem areas that cause your customers to turn away from a purchase.

Personalize customer experience

To create a personalized experience, you need information about the customer’s behavior, previous purchases, and social activity. This information is scattered across the web, and you need lessons in data science to bring it to one place. But, more importantly, data science helps you draw insights from information.

 

With this insight you can create different journeys for different customer segments. You utilize data points to map a sequence of options that would lead a customer to conversion. 80% customers are more likely to purchase if the eCommerce website offers a personalized experience.

 

For example: Your data analytics say that a particular customer has checked out hiking boots but has abandoned most purchases at the cart. Now you can focus on personalizing this customer’s experience by focusing on cart abandonment issues such as additional charges, postage shipping cost, payment options etc.

 

Several eCommerce websites use data to train their chatbots to serve as personal shopping assistants for their customers. These bots use different data points to give relevant shopping ideas.

 

You can also draw insights from data science to personalize offers, discounts, landing pages, product gallery, upselling suggestions, cross-selling ideas and more. 

Use data science for decision making & automation

The information provided by data science serves as the foundation for decision-making for eCommerce businesses. In a competitive market, a key piece of information can help you outshine your competitors, gain more customers and provide a better customer experience.

Using data science for business decisions will also help you improve the performance of the company. An informed decision is always better than an educated guess.
