Average

A statistic calculated by summing a set of data values and dividing by the number of values. Used to measure the centre of a sample of variable data.

example:

data values: 2, 5, 6, 4, 9, 3, 7, 8

sum of data values = 44

number of values = 8

average = 44 / 8 = 5.5

It can also denote the median, the mode, the geometric mean, and weighted means, among other things.
