Document Summary
Sample: a smaller set of cases a researcher selects from a larger pool and generalizes to the population. Researchers have 2 motivations for using probability or random sampling: the first motivation is saving time and cost. Census: an attempt to count everyone in a target population: qualitative researchers focus less on a samples representativeness or on detailed techniques for drawing a probability sample. Quota sampling: a type of non-random sample in which the researcher first identifies general categories into which cases or people will be selected, then he or she selects a predetermined number of cases in each category. Sequential sampling: a type of non-random sample in which a researcher tries to find as many relevant cases as possible until there is now new information or diversity from the cases. In sequential sampling, a researcher continues to gather cases until the amount of new information or diversity of cases is filled.
