Document Summary

Not a very good understanding of the population, study is to expand their understanding. Quota: ensures certain quotas are met, but then relies on haphazard (50% male, 50% female) still random however select number of equal number of male, female, youth. Purposive: researcher uses judgment to select cases with a specific purpose in mind. The purpose is les to generalize to the larger population, and more to gain a deeper understanding of specific types. Go to places where they can be found. Researcher continues sampling until all resources (time, financial, and energy) are exhausted. Sequential sampling: similar to purposive sampling, but the researcher stops when the amount additional information is small or negligible (more cost effective than purposive. )f you aren"t interested in the info you do not go get. Snowball: uses referrals or networks to draw samples (collect samples from it ) a first person than ask them to refer to you someone else.
