Statistics: Finding the Mean

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
