DEFINITION

The mean is a summary number that measures one type of midpoint in a range of numbers. In statistical terms determining the midpoint in a range of numbers is called the Measure of Central Tendency.

To find the mean of a set of numbers, or observations, we take the total value of all the members of the set and divide it by the number of items in the set. It is also known as the arithmetic average.
