Question

A middle school is trying to determine an appropriate theme for the spring dance. The principal wants to survey a group of students to determine the best option for the theme.



Which sampling method would MOST LIKELY be biased, random, and not representative of the population?



A.
Asking the entire football team.

B.
Asking the entire student body of the
7
th grade.

C.
Drawing names of
100
students from a school roster.

D.
Drawing the names of
5
students on the spring dance committee.

Answer 1

D.

Drawing 5 names from the spring dance committee is random only within a small, non‑representative group. Committee members have strong, similar views about the dance, so the sample is biased and won’t reflect the whole student body. Options A and B are biased but not random samples; C is a random, likely representative sample.
