Simpson's Paradox on Car Talk
Take Ray out to the ball game...
Car Talk Puzzler, NPR, 22 September 2012
Popeye batted .250 for before the All-Star break, while Bluto batted .300; Popeye batted .375 after the All-Star break, while Bluto batted .400. How did Popeye win his bet that he would have the better average for the season? Statistically minded listeners will quickly recognize this as an instance of Simpson's Paradox. Still, everything sounds like fun when Tom and Ray discuss it! You can read their solution here.
A famous real-life example of Simpson's Paradox with batting averages can be found here.
