Exercise

Inspect the data

The purpose of this chapter is to give you an opportunity to apply and practice what you've learned on a real world dataset. For this reason, we'll provide a little less guidance than usual.

The data from the study described in the video are available in your workspace as evals. Let's take a look!

Instructions
