How to calculate an average
mean = (sum of all values) ÷ (number of values)
Example: (85 + 90 + 78 + 92 + 88) ÷ 5 = 433 ÷ 5 = 86.6.
The median is the middle value when the numbers are sorted, and is less affected by outliers. For mode and more statistics, see the Mean, Median & Mode Calculator (coming soon).
