The Praying Mantis writing group carried out a statistical investigation over 6 days that found students at Insoll Avenue School were regularly littering and not using rubbish bins. Through recording data in a tally chart and creating a bar graph, the group determined that on one day over 300 pieces of rubbish were collected from a small area of the school grounds. The document expresses the group's frustration with having to clean up after other students and the problems littering causes like attracting pests. It concludes by stating the group worked cooperatively to complete their presentation on the issue.
