Dragging school bags around

Purpose

The purpose of this multi-level task is to engage students in an investigation following the statistical enquiry cycle.

Description of Mathematics

The background knowledge presumed for this task is outlined in the diagram below:

This task may be 'scaffolded' with either a focus on following the procedures given, or it may be given as an opportunity for students to sort and clean the data independently. The approach should be chosen in sympathy with their skills and depth of understanding.

Activity

Task: After a successful 'walk and wheels' week, students suggested they would be more likely to walk or ride to school if they didn't have to carry so much in their school bags.

A PE teacher countered that argument by suggesting that if they did walk or ride, they might get fitter and stronger and so not notice the weight of their bags so much.

Does bag weight affect how students travel to school? Use the data in the sample of year 9 and 10 students from CensusAtSchool, to investigate these ideas.
