In "Hardball," an amateur mathematician uncovers an equation that uses baseball statistics to identify which players are using performance enhancing substances. By analyzing player performance, he is able to determine when an athlete began using a performance enhancing substance.
Students will use a sabermetric statistic to identify a change point in a player's data, a point in time where the player's data becomes vastly different from the previous data trend.
