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 list and sharing this total out by how many 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 which is 47
Step 2 Now divide by the number of numbers, which is 10 to get 47 ÷ 10 = 4.7
The MEAN is 4.7
