1. What is Goal Against Average?

Goal Against Average (GAA) is a statistic used in ice hockey and other sports to measure a goaltender's performance. It represents the average number of goals allowed per 60 minutes of play.

2. How Does the Calculator Work?

The calculator uses the GAA formula:

\[ GAA = \frac{goals\_against \times 60}{minutes} \]

Where:

\( goals\_against \) — Total number of goals allowed
\( minutes \) — Total minutes played

Explanation: The formula standardizes the goals allowed to a 60-minute game duration for fair comparison between goaltenders.

3. Importance of GAA Calculation

Details: GAA is crucial for evaluating goaltender performance, comparing players, and making team roster decisions. Lower GAA indicates better performance.

4. Using the Calculator

Tips: Enter total goals allowed and total minutes played. Both values must be valid (goals ≥ 0, minutes > 0).
