Sports analytics

Sport generates cleaner data than almost any other subject: fixed rules, complete records, and a result at the end of every contest. That makes it the best available classroom for statistics, because you can check whether a model was right.

These clips cover the measures that changed how games are analysed, and the recurring lesson underneath them — that a season is short enough for luck to look exactly like skill.
