Pascoe wanted to study sexuality and gender identity develop among high school students, she selected what was considered to be an average high school in terms of population and family income, so that her findings from this case could be more generally applicable.Critical case sampling is a type of purposive sampling in which just one case is chosen for study because the researcher expects that studying it will reveal insights that can be applied to other like cases.
