Welcome to the latest episode of Hot Takedown, FiveThirtyEight’s sports podcast. The Hot Takedown crew is out of the office this week, so we’re bringing you a special blast from the past: our very first Stat School. In this episode, Neil dons the Stat Man cape, explaining the three ways to measure batting in order of increasing complexity: batting average, OPS (on-base plus slugging), and wRC+ (weighted runs created plus). Will Chad and Kate absorb all of his information and receive their certificates at the end of the course?

Here are links to the things we discussed during the show:
