Examples

  • Test scores 72, 85, 90, 66, 88, 94: sum 495 ÷ 6 = 82.5.
  • Daily steps 8,200, 10,400, 6,900: 25,500 ÷ 3 = 8,500.

Frequently asked questions

When is the average misleading?

One very large or small value pulls the mean towards it. For incomes or house prices, the median often describes a typical value better.

How do I average values that count differently?

Use the Weighted Average Calculator, which multiplies each value by its weight first.
