Hockey Statistics 101

As a Hockey Statistic, plus−minus (+/−, plus/minus) is a sports statistic used to measure a player’s impact on the difference between their team’s total scoring versus their opponent’s. In ice hockey, it measures a player’s goal differential. With the exclusion of power play and 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 calculated for each game played, but is more meaningful measure over a full season. The plus-minus is a direct result of overall team performance from both defensive and offensive team members.

A plus−minus is mainly used to analyze the performance of defenders and forwards who play a defensive role, while offensive forwards are more often measured by their scoring statistics (goals and assists). Defensemen tend to lead the plus−minus statistic more often than forwards, since they log more even-strength ice time.

When an even-strength or shorthanded goal is scored, every player on the ice for the team scoring the goal is credited with a “plus.” Every player on the ice for the team scored against gets a “minus.” A player’s overall total is calculated by subtracting the minuses from the pluses. A high plus total is taken to mean that a guy is a good defensive player. But it’s a very broad measurement and there has always been disagreement over how useful a statistic it is.

  • Power play goals are not used in calculating plus-minus.
  • Shorthanded goals are used in calculating plus-minus.
  • Penalty shot goals are not used in calculating plus-minus.

 

Goals against average: (GAA)

Goals against average (GAA) is a statistic used in ice hockey that is the sum of goals allowed per game by a goalie.

You can calculate it by multiplying the number of goals allowed by 60 and then dividing the sum by the total number of minutes played.

Save Percentage: (SV%, SVS%, SVP, PCT)

A goalie’s save percentage is a statistic that measures a goalie’s success based on the number of shots they faced.

You can calculate it by dividing the number of saves by the number of goals allowed.
