Question

Quizplus · Accepted Answer

The researcher is selecting participants from a list using a systematic approach of selecting every tenth person from a starting point. This is different from random sampling where each person on the list has an equal chance of being selected, or stratified sampling where the list is divided into subgroups and participants are randomly selected from each subgroup. It is also not cluster sampling, where groups are randomly selected and all members of that group are included in the study. Judgmental sampling involves selecting participants based on the researcher's personal judgment, which is not the case here. Therefore, the best choice is A) Systematic.
