The mean of a list of N numbers calculated bydividing their sum by N. The arithmetic mean is appropriatefor sets of numbers that are added together or that form anarithmetic series. If all the numbers in the list werechanged to their arithmetic mean then their total would staythe same.For sets of numbers that are multiplied together, thegeometric mean is more appropriate.
