This is an example of systematic random sampling, as the researcher selects every nth person from the list in a systematic manner. It is not simple random sampling because the selection is not completely random and not every member of the population has an equal chance of being selected. It is also not stratified random sampling because the population is not divided into strata based on certain characteristics. It is not stratified random sampling with differential probabilities because each member of the population has the same probability of being selected.
