There are several different types of **averages**.

An average is one number that represents a set of numbers.

The **MEAN **** **is a number which we calculate by adding up all the numbers in the set and dividing this total by how many numbers there are.

**Example**

Find the MEAN of this set of ten numbers: 5, 4, 8, 4, 3, 3, 8, 5, 1, 6

**Answer**

Step 1 Find the total of the set : 5 + 4 + 8 + 4 + 3 + 3 + 8 + 5 + 1 + 6 = 47

Step 2 Now divide the total by how many numbers in the set there are, which is 10: 47 ÷ 10 = 4.7

The **MEAN is 4.7**
