The owner of a local restaurant surveyed her staff on their preference of uniform color. The results are displayed in the table below. Which pair of samples is most representative of the preference of all the staff?

Uniform Color Survey

Sample 1 Sample 2 Sample 3

Beige 3 Beige 12 Beige 7

Blue 7 Blue 5 Blue 15

Black 10 Black 3 Black 18

Sample 1 and sample 2 are most representative because they are the same size.

Sample 1 and sample 3 are most representative because the relationship between preferences is consistent.

Sample 2 and sample 3 are most representative because the samples show a greater variability in preferences.

None of the samples are representative because none of the values remained constant.
