In the last two classes, we learned to compute statistical measures from a sample
of observations on a statistical variable. Moreover, we discussed how the sample
statistics can be used to arrive at a model for the entire population. Today, we discuss
how we can measure the *correlation*, i.e., the degree of linear association,
between two statistical variables.
Once again, let's try to learn the key concepts through an example.
