Learn data science by watching videos coding!
Most people learn best by doing, yet many online data science courses only ask you to memorize information, never to apply it. We took a different approach:
In guided projects, you'll use the data science concepts you just learned to answer real-world questions on real datasets.
In our interactive lessons, you'll learn a new concept, write code to apply it, and get feedback all on the same screen.
In a typical Dataquest session, you won't go more than five minutes without writing code!
Sound fun? Sign up and start learning R, Python, or SQL online today!

How Dataquest Works
Our entire learning experience runs in your browser — no installation necessary. Our introductory courses will teach you the fundamentals so you can learn Python or learn R online from scratch, no previous experience required.
There are no deadlines, so you can learn data science online at your own pace. And the best part? No videos. Just a clear path to learning.
Our Data Science Learning Platform
On Dataquest, you'll spend most of your time learning R and Python through our in-browser, interactive screens.
Typically, a screen presents a new data science concept on the left side, and challenges you to apply that concept by writing code on the right.
Before moving to the next screen, you submit your answer and get immediate feedback on the code you just wrote.
The Dataquest Community
All Dataquest students have access to our online data science community. Here, our trained moderators and other learners are ready to help you as you learn R and Python! This community is your go-to resource if you get stuck on a mission, encounter a platform issue, need advice, or want feedback on a project.
"Dataquest gave me a curriculum that covered everything I needed to learn, and a well-crafted route to get there." — Wes
