The Original Problem

This was the original problem posed to my students. The points A, B, C, D, and E are [b]strongly associated[/b] (why?) yet have a [b]correlation = 0[/b] (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 [color=#0a971e]Capture Point[/color] button. When you have captured many of these points, make a conjecture as to where these points lie.
