Mean Calculator
Find the average of a list of numbers by adding them up and dividing by how many there are.
This result is the average of the numbers entered, so a typical value in the list sits around this figure.
Formula
Mean = (sum of all values) ÷ (how many values there are).
How it works
Type numbers separated by commas. The calculator adds them, counts them, and divides the total by the count.
Worked example
For example, (4 + 8 + 15 + 16 + 23 + 42) ÷ 6 = 108 ÷ 6 = 18, so the mean is 18.
