How do you calculate goals against average.?

Answer 1

Goals scored against divided by games played equals goals against average.

Answer 2

Just Wind Me Up - That way works, but dividing once then multiplying is easier because you don't have to clear the calculator to get the GAA

(Minutes in Regulation Game/Minutes Played) x (Goals Allowed)

For example, I played roller hockey in a league where we played 45 minute games, and for this example, I gave up 2 goals in 38 minutes. So my GAA would be as follows:

(45/38) x 2 = 2.37 GAA

An overtime would be as follows, saying I gave up 3 goals, and the game ended 2:15 into overtime:

(45/47.25) x 3 = 2.84 GAA

For a season, it is calculated the same way, except the minutes played would be over the season. Say that season, in 10 games, I allowed 51 goals in 395 minutes (it's roller hockey, so it's going to be higher in my example, apply your stats as appropriate):

(45/395) x 51 = 5.81 GAA

You will need to know minutes and seconds and convert to a decimal to do this accurately. But I hope the examples helped show how to calculate GAA in any situation.

Answer 3

Goals scored against divided by minutes played.

Answer 4

GAA
It is calculated by dividing the number of minutes played by 60 minutes(one game) then dividing the goals against by that answer. It is typically given to two decimal places.

SV% - There is another statistic for NHL goalies because GAA is highly dependent on the team playing in front of a goalie, save percentage is usually considered a more accurate measure of a goaltender's skill. Save percentage (often known by such symbols as SV%, SVP, PCT) is a statistic that represents the percentage of shots on goal a goaltender stops. It is calculated by dividing the number of saves by the total number of shots on goal.

Although the statistic is called "save percentage", it is given as a decimal. Thus, .933 means a goaltender saved 93.3 percent of all shots he (or she) faced. National Hockey League goaltenders typically have a save percentage above .900,

Answer 5

You could add up the number of goals against and then divide it by the number of goals added up.
