If you’ve ever watched Major League Baseball, one of the feature points of the sport is the batting line-up that each team decides upon before each game.

Statistics, done correctly, allows us to extract knowledge from the vague, complex, and difficult real world. Wielded incorrectly, statistics can be used to harm and mislead. A clear understanding of statistics and the meanings of various statistical measures is important to distinguishing between truth and misdirection.

I didn’t think this still happened in 2018 . . . I opened my email to see 50 emails, from 50 different people, all with the same meaningless subject line. (In case you’re curious, it was “Re: Clerkships team.”)
