Question

The manager of an art gallery wants to bring in a new exhibit that will appeal to her customers. Which surveying method is most likely to produce a representative sample of the gallery's customers?

A) Surveying every 4th customer who is over the age of 50
B) Surveying everyone who enters the gallery alone
C) Surveying every 4th customer to leave the gallery
D) Surveying every other female customer

Answer 1

C

Explanation:

A doesn't make sense, because there are probably many people younger than 50.

Not B because that would be hard since there are probably not many people coming to the gallery by themselves.

Lastly,

Not D because that isn't very fair because since the women probably have different views than the men.

B makes the most sense because it does not rule anyone out and it lets everyone have an equal chance of being surveyed.
