Question 160473 • VA-Probability and Statistics

Which is the best example of selecting a systematic random sample?

Answer

Two distinct groups are formed from members of a population based on some characteristic, and a random sample of 50 people is selected from each group.

Members of a population are divided into representative groups, and then every 3rd group is selected until a sample of 100 people is formed.

Members of a population are listed in order of birthday, and every 5th person is selected until a sample of 100 people is formed.

The first 100 people to respond to a call for participants are selected.

Explanation

A systematic random sample is selected by choosing people at regular intervals from an ordered list, often after choosing a random starting point. In choice C, every 5th person is selected from a list ordered by birthday, which follows this pattern. Choice A is stratified sampling, while choice D is a voluntary-response sample.
