Researchers investigate bicycles stolen from a sixth-form college's cycle racks during the previous 12 months. Local police provide a total of 18 recorded thefts of students' bicycles from these racks during that period. Separately, students complete an anonymous questionnaire asking how many of their bicycles were stolen from the same racks during the same period, producing a total of 31 thefts.
