Q1.
Look at the table below. How expensive is the car which is 5 years old?
£2,500
£4
£5,000
Q2.
Referring to the same table, which of these statements is FALSE?
Correct answer: If there was a car which was 3 years old, it would definitely be worth £4,500
On average, the older the car, the more expensive it is
The data shows the age and price for 10 cars
The mode price of car is £4,000
Q3.
The scatter graph below shows the temperature and the number of ice creams sold at the beach on certain days. What was the temperature, in degrees, when 20 ice creams were sold?
10
20
25
Q4.
Referring to the scatter diagram above, which of the following statements is likely to be TRUE? Select one
Correct answer: A higher temperature caused the number of ice creams sold to increase
It's impossible that only 5 ice creams were sold when the temperature was 25 degrees - the person plotting the graph must have made a mistake!
More ice creams sold caused the temperature to increase
Since there are two different numbers of ice creams sold when the temperature is 25 degrees, there must be a mistake on the graph
