What does Wikipedia say about weighted average?
The weighted average is a generalization of the arithmetic mean and provides a characterization of a set of statistical data for the case where the values of the set have different significance, different weights. It is especially used to calculate the general arithmetic mean of a set that consists of several subsets. To calculate the weighted average, we need both the values whose average we want to calculate and their weights.
