What is an average?
The term average has a number of different meanings. Most generally, it is a single number used to represent a collection of numbers. In mathematics, "average" refers to the mean — specifically, the arithmetic mean. It is a simple statistical concept that's widely used in many areas.
The equation below is one of the more commonly understood definitions of the average:
Average = Sum / Count
Where the sum is the result of adding all of the
given numbers, and the count is the number of values
being added. For example, given the 5 numbers
2, 7, 19, 24, 25:
Average = (2 + 7 + 19 + 24 + 25) / 5
= 77 / 5
= 15.4 Frequently asked questions
