How It Works

How to Calculate Test Score Average

The test score average is the arithmetic mean of all test scores.

Formula

Average = (Test 1 + Test 2 + ... + Test N) / N

This gives equal weight to every test.

Worked Example

A student has four test scores: 85, 92, 78, 88.

test1 = 85test2 = 92test3 = 78test4 = 88
  1. 01Sum = 85 + 92 + 78 + 88 = 343
  2. 02Average = 343 / 4 = 85.75
