This practical task requires students to record data, which is read out to them, on a stem-and-leaf graph. The leaves are then ordered into a second graph and the graph interpreted.
Students study a table of test results percentages for a range of subjects. Students answer questions involving mean, median, mode and range. They also draw a stem-and-leaf graph.
Students construct a back-to-back stem-and-leaf graph for heights of trees. They then answer a question on range and make a statement comparing the heights of akeake and kōhūhū.

Students display data on a back-to-back stem-and-leaf graph to show the times taken to complete two walks. The longer of the two walks is then identified.
