1. What is Goals Allowed Average?

Goals Allowed Average (GAA) is a statistic used in sports, particularly in hockey and soccer, that represents the average number of goals a goalkeeper allows per game. It's calculated by dividing the total goals allowed by the number of games played.

2. How Does the Calculator Work?

The calculator uses the GAA formula:

Where:

• \( goals\_against \) — Total goals allowed by the goalkeeper
• \( games \) — Number of games played

Explanation: The equation provides the average number of goals the goalkeeper allows per game.

3. Importance of GAA Calculation

Details: GAA is a key metric for evaluating a goalkeeper's performance. A lower GAA indicates better performance, as it means the goalkeeper allows fewer goals on average.

4. Using the Calculator

Tips: Enter the total goals allowed and the number of games played. Both values must be positive numbers, with games played being at least 1.
