(mathematics)arithmetic mean - 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.

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