Question

Quizplus · Accepted Answer

The doctor has conducted simple random sampling, as she has chosen her sample randomly from the list of patients with a unique number assigned to each. Snowball sampling involves asking participants to refer other potential participants, cluster sampling involves dividing the population into clusters and randomly selecting clusters to sample from, and proportional stratified sampling involves dividing the population into strata based on relevant characteristics and selecting a proportionate sample from each stratum. None of these methods are evident from the given scenario.
