## 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.
