M3609: Paradoxes in Statistics in Splash! Spring 2014 (Apr. 12 - 13, 2014)
On a gameshow, there are three doors. Behind two are goats, and behind one is a wonderful surprise. You pick a door. The game show host opens a different door, revealing a goat. She asks if you want to change your mind and pick the third door in hopes of getting the wonderful surprise. Should you? We will discuss this tricky question and several other results in probability and statistics which seem paradoxical. The problem is not with mathematics, but with our understanding of concepts like independence and expectation and our lack of appreciation of confounding variables. Come learn, so that you will not be fooled by the data.
