In this worksheet, students practice drawing pie charts Key stage:  KS 4

GCSE Subjects:   Maths

Curriculum topic:   Statistics

Curriculum subtopic:   Statistics Interpreting and Representing Data

Difficulty level:   #### Worksheet Overview

When we are drawing a pie chart, we will normally be given a frequency table and have to link the frequencies to the angles we are going to draw,

Example: Here are the makes of some cars. Draw a pie chart to show this data.

 Make Ford Nissan BMW Mini Vauxhall Frequency 4 5 2 3 6

Step 1: Find out what the total frequency is

If we add the frequencies together, we get 4 + 5 + 2 + 3 + 6 = 20

This means our pie chart has to represent 20 cars in total.

Step 2: Work out what each car is worth as an angle.

All circles have 360°. If we split this into 20 parts

360 ÷ 20 = 18°

Step 3: Work out what each category is worth

There are 4 fords and each one is worth 18°. This means the Ford category is worth 4 x 18 = 72°

We can do this for all the other categories to get...

 Make Ford Nissan BMW Mini Vauxhall Frequency 4 5 2 3 6 Angle 72 90 36 54 108

We can now check we have done this correctly by adding up all the angles. We should always get 360.

Step 4: Draw the angles onto a pie chart and label the sectors.

I always like giving a key instead of writing the names in the sectors. It doesn't matter which you do, you'll still get the same marks either way. ### What is EdPlace?
