This is a graphic correlation lab exercise. It uses real data from a peer-reviewed journal publication by Lucy Edwards (1989). (I have manipulated the data set a little bit.) Students can finish the activity in two hours or less.

Determining whether students have met the goals

I have small classes, so it's easy for me to closely monitor student work. If necessary, I gently steer students in the right direction; thus, everyone ends up with something that approximates the "right" answer.
