Overview & Core Concept
Add your test scores together and divide by the number of tests taken.
Mathematical Formula
\bar{x} = \frac{x_1 + x_2 + \dots + x_n}{n}Step-by-Step Instructions
List all test scores
Write down each numerical score.
Add them up
Sum all test scores.
Divide by count
Divide by the number of tests.
Realistic Worked Example
Three Tests Example
Scores: 88, 92, 84.
- 88 + 92 + 84 = 264
- 264 / 3 = 88.0%
Average score is 88.0% (B+)
Key Takeaways
- If tests have different weights, use weighted average instead.
