Worked example

For values 4, 6, 8 and 10, add them to get 28 and divide by the four values. The arithmetic mean is 7. One unusually large or small value can pull the average away from what is typical.

Assumptions to check

Check that the numbers use compatible units and that missing values have not been treated as zero unless that is intended.

Important limitation

This is the arithmetic mean only. It does not calculate weighted averages, medians or other statistical measures.

Quick question

Can I calculate a weighted average?

Not with this version. It calculates the arithmetic mean of the values entered.
