15+ Free Data Science Courses, Tutorials and Certifications 2021

So you also want to become a Data Scientist?

Or you might have heard so many people talking about this field. Isn’t it?

The hype about Data Science is real and it’s all over the Internet. Most of it came from training platforms and institutes that are marketing it heavily.

But Data Science deserves that attention and that is the reason we thought to create a list of Free Data Science courses and certifications. So many people ask us to get some ideas on how to move into this world of Data and Analysis.

As per DataQuest, there is no Universal definition for Data Scientist. Every individual company takes a different approach to data and working models. This also means that similar positions in different companies may require you to work differently.

Being a field revolving around data and decisions, Data Science requires a solid understanding of concepts and evaluations. The free courses for Data Science mentioned in this article will be enough for you to cover the basic fundamentals. Some courses will even go further by letting you work on Data Science projects.

One thing to keep in mind is that this field requires the continuous evolution of concepts and ideas.  You can’t just learn through some courses and become a full-time Data Scientist. For that, you will have to work on real-world problems, face programming challenges, upgrade your skillset, play with tools, and more.

If you are now good with the introduction part then we can move to the list of free Data Science courses, guides, and tutorials.
