Refer to Scenario 5.2. Before administering the questionnaire, Moki discovered through talking to other sports rental businesses that, although retired males made up a small percentage of the area's population, they often rented kayaks and canoes. In light of this, Moki decided to include a minimum of 25 percent retired males in his sample. The final choice of respondents was left up to the interviewers. This sampling method is known as sampling.
