The campaign manager for one of the five candidates running for office in a city wants to conduct a survey to see how popular his candidate is among all voters in the city. He chooses the first name on a voter registration list at random and then goes through the list, choosing every 15th name after that, cycling through the whole list until he ends up where he started.
What type of sampling method did the campaign manager use?
A. Non-random sampling
B. Simple random sampling
C. Systematic random sampling
D. Stratified random sampling
I think its C
I agree.
The campaign manager used a sampling method called "systematic random sampling."
Systematic random sampling is a method of selecting a sample from a larger population by using a fixed interval. In this case, the campaign manager selected the first name on the voter registration list randomly and then chose every 15th name after that. By cycling through the whole list until returning to the starting point, the campaign manager ensured that each name on the list had an equal chance of being included in the sample.
Therefore, the correct answer is C. Systematic random sampling.
