Document Summary

Primary goal is to get a representative sample (small collection of units from a larger collection or population to produce generalizations about the larger group) Well-executed sample will produce results that are equally as accurate as trying to reach the whole population. Nonrandom sample: sampling elements are selected using something other than a mathematically random process. Researcher selects anyone he or she happens to come across. Cheap and quick but result in many systematic errors that misrepresent the population.

Researcher first identifies general categories into which cases of people will be selected, then selects predetermined number of cases into each category. Researcher can ensure that some differences occur but once quota sampler fixes the categories and number they use haphazard sampling. Researcher uses wide range of methods to locate all possible case of highly specific and difficult-to-reach population specific purpose in mind.
