Data Science Projects

If you’re learning data science, you're probably on the lookout for cool data science projects. Look no further! We have a wide variety of guided projects that'll get you working with real data in real-world scenarios while also helping you learn and apply new data science skills.

The projects in the list below are also designed to help you get a job! Each project was designed by a data scientist on our content team, and they're representative examples of the real projects working data analysts and data scientists do every day. They're designed to guide you through the process while also challenging your skills, and they're open-ended so that you can put your own twist on each project and use it for your data science portfolio.
 
You can complete each project right in your browser, or you can download the data set to your computer and work locally!  If you work on our site, you'll also be able to download your code at any time so that you can continue locally, or upload your project to GitHub.

The sky is the limit here and what you decide to look into further is completely up to you and your imagination!
