How to calculate an average

To calculate the arithmetic mean, follow these steps:

  1. Add all the numbers together
  2. Count how many numbers there are
  3. Divide the total by the count

Average = Total ÷ Count

For example, calculate the average of 4, 7, 2, 9, and 5:

  1. Total: 4 + 7 + 2 + 9 + 5 = 27
  2. Count: 5
  3. Average: 27 ÷ 5 = 5.4

The average of this list is therefore 5.4.

Examples

Example 1: Average test score

A student receives scores of 72, 80, 68, 90, and 75 on five tests.

Calculation: total 72+80+68+90+75=385, count 5, average 385÷5=77

Average score: 77

Example 2: Daily step count

One week of step counts is 6000, 8000, 7500, 9000, 7000, 6500, and 8500.

Calculation: total 52,500, count 7, average 52,500÷7=7,500

Average steps: 7,500

Example 3: Weekly sales

Sales over four weeks are 120, 150, 130, and 100 units.

Calculation: total 500, count 4, average 500÷4=125

Average sales: 125 units
