The language arts teacher wants to know whether the students in the entire school prefer a debate or a speech. The teacher draws a random sample from the following groups: A - All teachers in the school
B - All boys in each grade
C-All students in the speech club
D-All students in each grade

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

d- all students from each grade

Step-by-step explanation:

D, all students in each grade.

Step-by-step explanation:

If you did a random sample from the students in the speech club it will be biased because they will probably all say giving speeches because they are in the speech CLUB. You cannot do the teahcers because their answers will also be biased. If you do all the boys in each grade it will be biased only to what boys like and not girls or any other student in the grade. Therefore, using the process of elimination, the answer is D, you should take a random sample of all the students in each grade.
