Variance

The statistical difference between a golfer's established handicap index and their actual scoring performance in a given round or series of rounds. Variance analysis helps identify trends in a player's game and can indicate whether recent scores represent genuine improvement or temporary fluctuations. High variance might suggest inconsistency in performance, while low variance indicates steady, predictable play. Understanding variance helps golfers and instructors identify areas for improvement and set realistic performance expectations based on statistical patterns rather than single-round results.
