Question 9 • Statistics and Probability

Which of the following is an advantage of using systematic random sampling?

Answer
A
Systematic random sampling could inadvertently miss patterns in the population.
B
Systematic random sampling uses clusters, which are close in proximity, making data collection easier.
C
Systematic random sampling does not require a finite population size.
D
Systematic random sampling reduces sampling variability.

Explanation

Systematic random sampling selects members at regular intervals from an ordered list after choosing a random starting point. This can spread the sample across the population and reduce sampling variability compared with a purely random sample. Using nearby clusters describes cluster sampling, while the possibility of missing a repeating pattern is a disadvantage of systematic sampling.
