19 A comparison of the masses (in kg ) of convertible cars was made using the Large Data Set.
A sample of 20 masses was chosen from both the 2002 data and the 2016 data.
The masses of the 20 cars in each sample were used to create a box plot for each year.
The box plots were labelled Box Plot A and Box Plot B as shown in the diagram below.
