Creating Pie Charts

Show your working for calculations. Give angles in degrees and percentages to the nearest whole number where needed.

Understanding pie charts

1.Which kind of information is usually most suitable for a pie chart?

Daily temperatures recorded over a month
Categories that make up a single total
The heights of every student in a year group
A comparison of two unrelated measurements

2.A full pie chart represents one complete circle. What is the sum of the angles of all its sectors?

90°
180°
360°
720°

3.Choose all the features that help make a pie chart clear and accurate.

Sector sizes proportional to the data
Labels or a key that identify the categories
A clear title
Three-dimensional effects, even if they distort sector sizes

Reading

Art

4.In a survey of 150 students, 45 chose music as their preferred after-school activity. What percentage of the students chose music?

5.In a survey of 150 students, 60 chose sport as their preferred after-school activity. Calculate the angle for the sport sector in a pie chart. Show your calculation.

6.For a survey of 150 students, the activity counts were music 45, sport 60, reading 30 and art 15. Complete the percentage and angle for each activity.

Drawing and interpreting pie charts

7.Use the survey counts below to draw a pie chart. Include a title and identify each sector. Music: 45 students; sport: 60; reading: 30; art: 15. Total: 150 students.

8.In a survey of 150 students, 60 preferred sport, 45 preferred music, 30 preferred reading and 15 preferred art. State two conclusions you could make from the results.

9.A pie chart made from a complete data set has sector angles totalling 348°. Explain why this is a problem and give one way to find and correct the error.

10.A school meeting audience wants to compare how one group's activity preferences make up the whole group. Give one reason a pie chart could be useful, and one limitation to consider.
