Question

Quizplus · Accepted Answer

Sophia is using systematic sampling, where she is selecting every 10th name from a list. This is not stratified random sampling because she is not dividing the alumni into distinct groups before selecting from each group. It is also not cluster sampling because she is not randomly selecting groups of alumni to survey. Finally, it is not simple random sampling because the names are not selected randomly without any pattern or system.
