The Original Problem
This was the original problem posed to my students. The points A, B, C, D, and E are strongly associated (why?)
yet have a correlation = 0 (why?)
Slowly drag point A and find other possible locations for point A that keeps the correlation = 0. By careful dragging, you
should be able to find many of them. When you find such locations, click on the Capture Point button.
When you have captured many of these points, make a conjecture as to where these points lie.
