Plus-minus

Plus–minus (+/−) is an ice hockey statistic that measures a player's goal differential. With the exclusion of penalty shot goals, when an even-strength or shorthanded goal is scored, the plus–minus statistic is increased by one ("plus") for those players on the ice for the team scoring the goal; the plus–minus statistic is decreased by one ("minus") for those players on the ice for the team allowing the goal. The plus–minus statistic is not affected by power play goals. Also, whether or not the net is empty does not matter for purposes of plus–minus.
