Data science has been one of the fastest-growing fields in recent years.

It is a field that offers great job prospects and high earning potential, but it can be hard to know where to start.

It affects our everyday lives, from the ads we see when checking out at a grocery store to how well (or not) our national football team is doing and what it means for your wallet or purse.

This means that you need to learn data science, and learning about it is just a Google search away.

Luckily for all of us, there are many MOOCs (online courses) on the subject available now.

This means that if you’re interested in becoming a Data Scientist or expanding your knowledge, this post will help you choose which course might be best for you.

I have selected courses from Datacamp, Coursera, edX, Udemy, Codecademy, and Udacity which I consider to be the best out there at this time.

Some of these are beginner-level while others provide a more in-depth look so choose wisely.

Here are 15 of the best online data science courses from around the web:
