The geometric mean for a sequence of N items is the 1/Nth power of the cumulative product for the items.
geometric mean of N items =
= ((cumulative product) ^ (1/N)) =
= ((X1 * X2 * …* Xn) ^ (1/N))
If all of the items in the sequence equal X, then the geometric mean is X.
Limitation:
• If one of the items in the sequence is a 0 then the geometric mean will be 0, which would not be terribly informative.
