Quizplus · Accepted Answer

Quota sampling allows the researcher to ensure adequate representation of certain subgroups in the sample, in this case, socioeconomic status and type of health insurance. This will help to prevent the confounding of results by these variables and increase the generalizability of the findings. Cluster sampling involves dividing the population into clusters and randomly selecting clusters to sample from, but it does not guarantee representation of specific subgroups. Network sampling involves using social networks to identify and recruit participants, which may not be appropriate for this study. Theoretical sampling is used in qualitative research to guide data collection based on emerging theories, and is not appropriate for this study.
