Quizplus · Accepted Answer

The sampling technique described in the question is systematic sampling, which involves selecting every nth element from a sampling frame after randomly selecting a starting point. This is different from simple random sampling, where each element in the sampling frame has an equal chance of being selected, and from cluster sampling, where the sampling frame is divided into clusters and only certain clusters are selected. Cross-tabulation sampling and a census are not recognized statistical sampling techniques.
