How the average is calculated

The arithmetic average is found by adding the values and dividing the total by the number of values. It works well when each observation should have equal weight. Enter the values you want to compare and review the resulting mean.

Values of 10, 20 and 30 have a total of 60 across three observations, so the average is 20. A very large or very small value can pull the average toward itself, which matters when interpreting the result.

For datasets with extreme values, compare the mean with the median or other summary measures to get a fuller picture.
