Golf STATS: Strokes Gained Explained

In this video I talk about the statistic that changed golf: Strokes Gained. Strokes gained was created my Mark Broadie a Colombia business school professor.

Strokes gained is a normalized metric that allows us to compare type of shot apples to apples. They are compared using fractions of strokes. This is very similar to how wins above replacement is used in baseball.

Strokes gained is also an aggregated / normalized metric. In order to get strokes gained, we compare each shot, hole, round, and tournament to the average. If a player shoots 72 and the average score for the day is 73, then they have +1 strokes gained on the round. Players who play better than average should always have positive total strokes gained and players who perform worse than average should always have negative strokes gained total.
