Question

Quizplus · Accepted Answer

Systematic sampling involves selecting every kth element from a list of data items, where k is a fixed interval. This method does not require a list of enumerated data items, unlike other methods like simple random sampling or stratified sampling. Option A is incorrect because choosing the third person listed on every fifth page of the phone book is systematic sampling, not stratified sampling. Option C is incorrect because convenience sampling involves selecting individuals who are convenient or readily available for the study, not necessarily shoppers in convenience stores. Option D is incorrect because judgment sampling involves selecting individuals based on the researcher's judgment or criteria, and it is not an example of true random sampling.
