Representation of data — practice question
On last Saturday, a team cycling contest involving teams of 11 cyclists was held. Each cyclist’s finishing time for the course was measured to the nearest minute. The times for the cyclists in two teams, the Linnets and the Puffins, are listed in the table below.
(a)[4]
Represent this data by drawing a back-to-back stem-and-leaf diagram, with Linnets shown on the left-hand side.
(b)[2]
Find the interquartile range of the times taken by the Linnets.
(c)[3]
On the grid below, draw box-and-whisker plots to show the information for the Linnets and the Puffins.
(d)[1]
Make one comparison between the times taken by the Linnets and the times taken by the Puffins.
