Average

Also known as the arithmetic mean, average is the sum of a collection of numbers, divided by the total amount of numbers. For example, assume we have the following collection of numbers: "1, 2, 3, 4, 1, 2, 3". The sum of these numbers is 16, 16 divided by 7 is 2.28, therefore 2.28 is the average of these numbers.
