Quizplus · Accepted Answer

The sampling method described is cluster sampling because the researcher is selecting a random sample of elementary school districts and testing all sixth graders in those districts. It is not stratified random sampling because the researcher is not dividing the population into strata based on characteristics such as socioeconomic status or race/ethnicity. It is not quota sampling because the researcher is not selecting participants in predetermined proportions based on their characteristics. It is not convenience sampling because the researcher is not selecting participants based on their availability or willingness to participate.
