A teacher wants to know whether the students in the entire school prefer watching television or playing outdoor games after school. The teacher draws a random sample from the following groups:All school teachersAll students on the football teamAll boys in each gradeAll students in each gradeWhich of the following groups best represents the population from which the teacher should take a random sample to get the best results for her survey?A. All school teachersB.. All students on the football team C..All boys in each gradeD. All students in each grade
Accepted Solution
A:
D. All students in each grade. It can't be A since the survey is for the students, it defeats the purpose. It can't be B and C since those are too biased. Basing the student population on one factor like gender and sports is not logical in the context of this survey.
