I have an updated and revised (slower and otherwise improved) version of this video available at: youtu.be/cTolF3G5a1I

A look at the Pearson correlation coefficient (r), the coefficient of determination (r^2), some of their properties and a few examples.

One of the data sets used is estimated from a figure given in:

Singer et al. (2004). Empathy for pain involves the affective but not sensory components of pain. Science, 303:1157--1162.
