## arithmetic mean

(mathematics)
The mean of a list of N numbers calculated by dividing their sum by N. The arithmetic mean is appropriate for sets of numbers that are added together or that form an arithmetic series. If all the numbers in the list were changed to their arithmetic mean then their total would stay the same.

For sets of numbers that are multiplied together, the geometric mean is more appropriate.
