PATH
Data Scientist
Learn how to make inferences and predictions from data.
This path covers everything you need to learn to work as a data scientist using Python.
You'll learn the Python fundamentals, dig into data analysis and data viz, query databases with SQL, study statistics, and dig into building machine learning models all over the course of this carefully designed course path.
It's designed so that there are no prerequisites and no prior experience required. Everything you need to learn, you'll learn on this path!
As you learn, you'll apply each concept immediately by writing code right in your browser that's automatically checked by our system to give you near-instant feedback on your progress.
We think the best way to learn is to learn by doing, so you'll be challenged every step of the way to really apply the concepts you're learning, and you'll build a variety of projects using real-world data to solve real data science problems.
By the end of this path, you'll have the skills you need to work as a data scientist, and you'll be comfortable with things like:
