How This Calculator Works
The mean, often called the average, is calculated by adding all the numbers together and dividing by the number of values. This calculator also shows the total count and sum of the values entered.
Formula
Mean = Sum of Values / Number of Values
Example
If the values are 10, 15, 20, 25, and 30, the total sum is 100. Since there are 5 values, the mean is 20.
