Leo DeCaprio, the ages of his girlfriends: Regression in real life.

Ok, so this from Reddit:

This, of course, inspired me to cook up an example for Psych Stats, in the catty spirit of this very judgmental regression about the life and love of Dennis Quaid.

Here is a Google Sheet that contains ALL of the data featured above, as well as a sheet that contains JUST the GF's age when they first started dating. Maybe this example is a little better for our younger students who haven't heard of Dennis Quaid. Anyway, enjoy.
