#### 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 that we calculate by adding up all the numbers in the set and dividing this total by how many numbers there are.

Here are three pupils' scores in a weekly spelling test across 6 weeks:

Example

Find the mean score from week 1.

Step 1: Find the total score from week 1:

9 + 7 + 2 = 18

Step 2: Now divide the total by how many numbers there are in the set, which is 3:

18 ÷ 3 = 6

The mean score from week 1 is 6

Easy, right?

Let's have a go at some questions then!
