Are you ready to jump into the exciting world of Data Science? Whether you’re a beginner or an experienced programmer, this Best Courses Guide (BCG) is here to help you find the top online courses to get you started.
Data Science is a rapidly growing field that combines statistics, programming, and domain expertise to extract insights from data. With the right skills and knowledge, you can unlock the power of big data and make a real impact in your career. So, grab a cup of coffee and let’s start exploring Data Science together!
One note about this guide: Although data science is typically considered a superset of data analytics, data analytics has been getting a lot of traction in its own right, so I’ve also included courses that explicitly focus on data analytics in this BCG. We’ve also made sure to include Python and R as they are the most popular programming languages used for data science.

What is Data Science?
Data science is a field that utilizes scientific induction to extract general principles from specific observations. With the vast amount of data generated daily in the digital age, it would be impossible for humans to sift through them all to discover trends. This is where data scientists come in, offloading the difficult computational work to machines through machine learning or deep learning.
However, data scientists are needed to ensure that the data fed to the machines is clean and the right machine is chosen, and to communicate the findings to those who may not be as technically inclined. This challenging and rewarding field has been gaining popularity, being hailed as the sexiest job of the 21st century by HBR and paying a median salary of $159K per year in the United States.
Data analytics, a subset of data science, has also been gaining traction, and Python and R are the most popular programming languages used in the field. With data galore and new technologies emerging every day, data science is set to become an increasingly important and exciting field for years to come.
My Experience with Data Science
I (Elham) built this guide in collaboration with my colleague @manoel.
We both come from computer science backgrounds and are prolific online learners, having completed about 45 MOOCs between us. Additionally, Manoel has an online bachelor’s in computer science, while I am currently completing my foundation in computer science. In fact, data science is the primary reason I’m interested in CS!

Best No-Coding Data Science Course on Process Mining (Eindhoven Tech)
This course, Process Mining: Data science in Action is quite different from the other courses in this guide in terms of contents. For starters, this course won’t teach you coding. What it does teach you is the key theoretical tools and analytical skills needed to perform process mining — not “just” data mining, we are higher in the ladder of abstraction here, and we’re entering specialized territory. This course asserts that processes should be considered first-class citizens, to the same extent as data, and therefore, that they should be put through the same scrutiny. The course provides easy-to-use software, real-life data sets, and practical skills for you to directly apply the theory in a variety of application domains. More on process mining: process mining is a technique used to analyze and track processes. Its goal is to help organizations turn event data into actionable insight. Example applications include: analyzing treatment processes in hospitals, understanding the browsing behavior of customers using booking sites, analyzing failures of a baggage handling system, and improving the user interface of an X-ray machine. After taking this course, you’ll be able to run process mining projects and have a good understanding of the Business Process Intelligence field. You’ll also benefit from practical data science knowledge that can be applied directly to analyze and improve processes in a variety of domains. So this course has well defined scope within data science that may be suitable for learners that already have a background in the field and would like to explore an additional facet. The course assumes a basic understanding of logic, sets, and statistics at the undergraduate level prior to taking this course. You’ll learn:

Best Data Science and Machine Learning Course for Confident Python Users (Udemy)
If you are already familiar with Python programming and want to start straight away with practical data science (especially machine learning), this course is for you. This Udemy course is the most comprehensive all-in-one package in this guide— at least, in terms of breadth. What I like the most about this course is that it goes through the history, theory and intuition behind each machine learning algorithm before you start applying it, unlike some courses out there. This unfortunately (or fortunately for nerds like us) means the course will expose you to math and statistics, but nothing too overwhelming. Knowing some highschool mathematics and statistics should be enough to be comfortable taking this course. You’ll learn:

Best Courses Guides Methodology
I built this guide following the now tried-and-tested methodology used in previous Best Courses Guides (you can find them all here). It involves a three-step process:
- Research: I started by leveraging Class Central’s database with 250K online courses and 250K reviews. Then, I made a preliminary selection of Data Science courses by rating, reviews, and bookmarks.
- Evaluate: I read through reviews on Class Central, Reddit, and course providers to understand what other learners thought about each course and combined it with my own experience as a learner.
- Select: Well-made courses were picked if they presented valuable, engaging content and fit a set of criteria: comprehensive curriculum, affordability, release date, ratings and enrollments.
After going through this process — combining Class Central data, our experience as lifelong learners, and a lot of editing — we arrived at our final guide. So far, we’ve spent more than 21 hours building this article, and we intend to continue updating it in the future.
Fabio and Pat revised later versions of this article.
