Question
Students collected data about members of their favourite sporting teams.They were asked to collect data for their height, years at the club and age, and display the data using methods they had been studying. Four students were observed.Which student used a method of display that was not appropriate for the data?Question 1Select one:a.Ali used 3 line graphs.b.Trudy used a stem and leaf plot for the heights and dot plots for the years at the club and ages.c.Siobhan used stem and leaf plots for years at the club and ages, and a dot plot for height.d.Hugo used histograms for years at the club and ages, and a dot plot for height.
Solution
The student who used a method of display that was not appropriate for the data is Ali. Line graphs are typically used to display data that changes over time. In this case, the data collected (height, years at the club, and age) are not time-series data, so line graphs would not be the most appropriate method of display. The other students (Trudy, Siobhan, and Hugo) used stem and leaf plots, dot plots, and histograms, which are all appropriate for displaying this type of data. Therefore, the answer is a. Ali used 3 line graphs.
