In ice hockey, it measures a player's goal differential. When an even-strength goal 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. Power play or penalty shot goals are excluded. An empty net does not matter for the calculation of plus--minus.
