A teacher wants to know whether the students in the entire school prefer watching television or playing outdoor games after scho
ol. The teacher draws a random sample from the following groups: All school teachers
All students on the football team
All boys in each grade
All students in each grade
Which 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 teachers
B.. All students on the football team
C..All boys in each grade
D. All students in each grade
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.
