Worksheet Overview

QUESTION 1 of 10

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 frequencyies 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

260 ÷ 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.

The first step when we draw a pie chart is to...

Once we have what each data point is worth (in degrees)...

  • Question 1

The first step when we draw a pie chart is to...

CORRECT ANSWER
EDDIE SAYS
We need to find out how much we are splitting the circle into. If we add up the frequencies and divide 360 by this, we find what angle each data point is worth.
  • Question 2

Once we have what each data point is worth (in degrees)...

CORRECT ANSWER
EDDIE SAYS
Since we don't draw the individual data points on a pie chart, we need to know how many are in each category. For example, If we had 10 cars and each was worth 6° The car category would have an angle of 10 x 6 = 60°

How many adults were in the survey?

CORRECT ANSWER

What is each child worth on the pie chart? (don't worry about units)

CORRECT ANSWER
4
EDDIE SAYS
We have 90 children to put into a circle that has 360 degrees. 360 ÷ 90 =

The favourite programmes of some adults were collected and are shown below.

What angle do I need to draw for each category

CORRECT ANSWER
 Angle
Line of Duty
Killing Eve
Game of Thrones
Emmerdale
Bodyguard
EDDIE SAYS
Each adult was worth 6°. All we have to do is multiply the frequency by the angle to find the angle for the category. Remember, once you have done this, you can check your answers by adding up the angles. They should always make 360
  • Question 6

Which of the two pie charts have been drawn correctly?

CORRECT ANSWER
Left one
EDDIE SAYS
You need to be able to spot if the angles you have drawn are correct. If we compare Line of Duty (Orange) and BodyGuard (Yellow). The orange sector should be 5 times the size of the yellow one. In the right-hand pie chart, they're about the same size so this cannot be drawn correctly.

What angle do I need to draw for each category

CORRECT ANSWER
 Angle
Walk
Car
Bus
Cycle
EDDIE SAYS
Each child was worth 4°. All we have to do is multiply the frequency by the angle to find the angle for the category. Remember, once you have done this, you can check your answers by adding up the angles. They should always make 360

Which of the two pie charts have been drawn correctly?

CORRECT ANSWER
Right one
EDDIE SAYS
You need to be able to spot if the angles you have drawn are correct. Our data says that the biggest angle that is drawn should be the one for cycle.
