In order to assess reactions to a proposed tuition hike at her college Ariana sent a questionnaire to every fifteenth person in the college registrar's alphabetical listing of all currently enrolled?

Answer 1

Ariana's method of sampling by sending a questionnaire to every fifteenth person in the college registrar's alphabetical listing is an example of systematic sampling. This technique ensures a structured approach to gather feedback while maintaining randomness, as the selection is spaced apart. However, it may inadvertently exclude certain groups if the alphabetical arrangement correlates with specific Demographics, potentially biasing the results. Overall, it's a practical way to gauge reactions, but the sampling method should be considered when interpreting the findings.
