Weighted geometric mean
In statistics, given a set of data, - X = { x1, x2, ..., xn}
and corresponding weights, - W = { w1, w2, ..., wn}
the weighted geometric mean is calculated as
Note that if all the weights are equal, the weighted geometric mean is the same as the geometric mean. Weighted versions of other means can also be calculated. Probably the best known weighted mean is the weighted arithmetic mean, usually simply called the weighted mean. Another example of a weighted mean is the weighted harmonic mean.
