Question

PPPPPPPPPLLLLLZZZ HAAAALLLPPP MEEEEHH IM TIIIIIIIIMMEEEDDDDD

The social studies teacher wants to know whether the students in the entire school prefer a model United Nations activity or a student government activity. The teacher draws a random sample from the following groups:

All teachers in the school
All boys in each grade
All students in each grade
All students in the social studies club

Which group best represents the population he should take a random sample from to get the best results for his survey?

Answer 1

all students in the club

Explanation:

Answer 2

C. All students in each grade

Explanation:

Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.

Hope this helps!
