Probability and nonprobability are the two general categories of sampling. Probability sampling uses random selection, whereas nonprobability sampling does not. For example, if you wanted to study the effects of divorce on the psychological development of adolescents, you could gather a population of a certain number of adolescents whose parents were divorced.

POPULATION AND SAMPLING
Probability and nonprobability are the two general categories of sampling. Probability sampling uses random selection, whereas nonprobability sampling does not. For example, if you wanted to study the effects of divorce on the psychological development of adolescents, you could gather a population of a certain number of adolescents whose parents were divorced. Then, out of that population, you could randomly select 25 of those people. If you wanted to use nonprobability sampling, you would choose specific people who had met predetermined criteria. Consider your own proposed study: Which of these sampling techniques might be best for your purposes?
In this Discussion, you identify the population, sample, and sampling technique for your study. You then consider ethical or cultural issues related to the population that you should address.

TO PREPARE
· Review the Learning Resources on sampling in research and on ethics related to vulnerable populations.
BY DAY 3
In this Discussion, you identify the population, sample, and sampling technique for your study. You then consider ethical or cultural issues related to the population that you should address.
Please use the Learning Resources and the NASW Code of Ethics to support your post (i.e., cite and reference).
BY DAY 6
Respond to two colleagues by providing feedback on their choice of population, sample, and sampling technique. How do their choices fit with the research question and research methodological approach?
Please use the Learning Resources and the NASW Code of Ethics to support your response (i.e., cite and reference).
