In mathematics, a measure of the average of a
number of terms or quantities. The simple
arithmetic mean is the average value of the
quantities, that is, the sum of the
quantities divided by their number. The
weighted mean takes into account the
frequency of the terms that are summed; it is
calculated by multiplying each term by the
number of times it occurs, summing the
results and dividing this total by the total
number of occurrences. The geometric mean is
the corresponding root of the product of the
quantities. In statistics, it is a measure of
central tendency of a set of data.
