A school principal wants to find out the opinion about the playground equipment from the students at the school. Which method produces the most representative sample for the survey? A Randomly survey 150 students playing out at recess. B Randomly e-mail 150 parents of students. C Mail surveys to all homes within 5 blocks of the school. D Survey each teacher in the building.
They are students, and they are on the playground, so it makes more sense than e-mailing parents or teachers or mailing it to all houses. A will get the best results. (sorry it's hard to explain)
