Dataquest is an online data learning portal that provides thousands of material and quizzes that can improve your data science skills like Python, R, SQL, Git, and more!

Learn by watching videos coding!

Most people learn best by doing, yet many data science courses only ask you to memorize information, never to apply it. We took a different approach:

1. In interactive lessons, you'll learn a new concept, write code to apply it, and get feedback all on the same screen.
2. In guided projects, you'll use the concepts you just learned to answer real-world questions on real datasets.
3. In a typical Dataquest session, you won't go more than five minutes without writing code!
