  # Statistics: Finding the Mean

In this worksheet, students calculate the mean of a given set of data. Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   Mean, Median, Mode and Range

Difficulty level:   #### Worksheet Overview

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

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
