This SQL for Data Analysis course is also completely free and teaches SQL for Data Analysis. SQL is used for managing data and if you want to learn or brush up on your SQL skills, this is the best course.

In all these courses, I enrolled and then check their content quality. So, when I enrolled in this course, I found that this is an in-depth course and has 7 lessons.

The first lesson covers SQL basics such as Why SQL is essential, Types of Statements, SELECT & FROM, LIMIT, ORDER BY, WHERE, Arithmetic Operators, and many other topics.

The next two lessons cover SQL Joins and Aggregations.

Subqueries, Table Expressions, and Persistent Derived Tables are also covered in this course. After that, the instructor Derek Steer explains how to clean the data using SQL and advanced SQL such as SQL window function, Advanced Joins, and Performance Tuning.

Overall, without paying any course fee, this course will cover SQL in detail.

3. Bayesian Statistics: From Concept to Data Analysis– Coursera

Rating-	4.6/5
Time to Complete–	12 hours
Best For-	Intermediate

This Bayesian Statistics: From Concept to Data Analysis is a Free to Audit course offered by the University of California, but this course is not for beginners.

To audit this course for FREE, click on the “Enroll for FREE” button. And new popup will appear where they will provide payment details, but at the bottom, you will see an option “Audit the Course”. Click on it. And you will be redirected to the course material.

When I audited the course for free to check its content quality, I found that they have divided the course into a 4-week plan.

In the first week’s plan, they cover Probability basics and Bayes Theorem. You will also learn Bernoulli and binomial distributions this week.

I don’t know why they divided it into 4 weeks because the videos are not very long. Most of the videos are 6-10 minutes.

The next week, you will learn Statistical Inference. This course uses R Programming instead of Python. There is a separate video on R Programming introduction.

In the third week, you will learn Priors and Poisson Data. In the last week, they explain Linear Regression.

Drawback-

• If you audit this course for free, they will lock the quizzes and assignments. Only course material is available for free.

You Should Enroll if-

• You should have prior knowledge of basic statistics class (for example, probability, the Central Limit Theorem, confidence intervals, linear regression) and calculus (integration and differentiation).

4. Data Analysis with R- Udacity

Rating-	NA
Time to Complete–	2 Months
Best For-	Intermediate

This Data Analysis with R is an intermediate-level free course to learn data analysis using R programming. I found that Udacity FREE courses don’t lack in quality compared to other platforms’ free courses.

This course has 9 lessons and 1 project. The course begins with EDA (exploratory data analysis) Basics. The instructor explains why you need to learn EDA and the goals of EDA.

After that, there is a separate lesson on R Programming basics. This is not a very detailed explanation of R Programming but explains how to install RStudio on Mac and Windows, RStudio Layout, Demystifying R,  R Markdown Documents, etc.

The next six lessons are on exploring one variable, two variables, and multiple variables. Problem sets are also included after each lesson.

Then, there is one case study on Diamonds & Price Predictions where the instructor showcases how to use a linear regression model to predict diamond prices. This lesson might be tough for you if you don’t have previous statistical knowledge.

At the end of this course, there is one project, where you have to use R Programming and perform exploratory data analysis for exploring relationships in one variable to multiple variables.

As this course is free, that’s why the project feedback feature is locked. That means you have to finish the project by yourself.

Drawback-

• Doesn’t provide a certificate.

You Should Enroll if-

• You have prior knowledge of statistics.

5. Exploratory Data Analysis in Python– DataCamp

Rating-	NA
Time to Complete–	4 hours
Best For-	Intermediate

In DataCamp, full courses are not free. Only the first lesson of all courses is free. Similarly, in this Exploratory Data Analysis in Python course, you will get access to its first lesson free of cost. So, in the first lesson of this course, you will learn how to read the data, check for errors and special cases, and prepare data for analysis.

This first lesson will help you to understand the process of Data Cleaning. You can watch this free lesson as a YouTube tutorial, but this one lesson will not be enough to understand data analytics in detail.

I don’t like this feature of DataCamp. They should either give a full course for free or lock the full course. But, we can’t do anything, so you can check the first lesson of this course and if you find it useful, you can go for a DataCamp subscription. It’s totally up to you.

Drawback-

• Very few learning materials are available for free.

You Should Enroll if-

• You have prior Python knowledge.

Which Course do I Recommend?

I have enrolled in all these 7 courses just for checking the content, I would suggest Intro to Data Analysis by Udacity for beginners. This course will provide basic fundamentals of data analytics and the project covered in the course will be beneficial for your Resume.

And for intermediate learners, who already knew some statistics and Programming knowledge, I would suggest Data Analysis with R by Udacity. In this course, you will work on 1 case study and 1 project.

But if you don’t want to learn R Programming, then you can check Exploratory Data Analysis in Python by DataCamp. The problem with this course is that the full course is not free. Only the first lesson is free.

Now, it’s time to wrap up.
