Average Definition

The term “Average” describes a value that should represent the sample. An average is defined as the sum of all the values divided by the total number of values in a given set. It is also known as the arithmetic mean. Let us consider a simple data to find the average.

Given set of values: 1, 2, 3, 4, 5.

Average = Sum of all the values/ total number of values

Average = (1+2+3+4+5)/5 = 15/5 = 3

Mean Definition

A mean is a mathematical term, that also describes the average of a sample. In Statistics, the definition of the mean is similar to the average. But, it can also be defined as the sum of the smallest value and the largest value in the given data set divided by 2.

Mean = (Sum of the smallest value and the largest value)/ 2

Let consider the same example given above:

The smallest value is 1, and the largest value is 5

Therefore, mean = (1+5)/2 = 6/ 2 = 3

You can observe that, the result of both the average and mean for the given data set is similar.
