4m by 3.5m. The paper comes in rolls of 100cm by 500cm costing £3.59 each.

Will you be able to buy the paper? Explain why.

2.1 Extracting and Interpreting Data from Graphs

Western Africa. How many people earn

less than $500?

Q2 The line graph shows the speed of a bike

from the start of a race.

a. What speed was the bike going after

3 seconds?

b. What distance did the bike cover after

6 seconds?

c. Can you explain why the graph starts

low and gains height quickly?

2.2 Making and Explaining Decisions based on Graphical Information

Q1 You have been asked to arrange a sports day for

your school. Based on the bar graph provided,

what is the best sport to organise?

Give a reason for your answer.

Q2 The line graph shows the rainfall for two

cities. If you had to choose between the

two to go on a cycling holiday, which

month would you go, and where would

you go?

Give a reason for your answer.

2.3 Making and Explaining Decisions based on Probability

Q1 The following are results from a school for the number of pupils who passed

their exams:

Mathematics – out of 80 pupils, 65 of them passed

Art and Design – out of 60 pupils, 40 of them passed

If you were the deputy head teacher, which subject would you focus on more to

improve the number of pupils passing? Explain your answer.

Q2 A business carried out a survey to find out where people were spending their
