Document Summary
Sampling - the process of selecting people (or elements) for inclusion in a research study. Generalizability - the ability to project the results of one study to a much larger reality. Also called external validity - the extent to which a study"s findings hold true outside of (external to) the particular context of the research. Many factors that make a study more or less generalizable. Population of interest - the population the study aims to investigate in the first place. Every study investigates at least one or more parameters - characteristics or features of the population of interest. The broader the population of interest, the more generalizable the results. A random sample is more generalizable than nonprobability samples such as. If a study is done over many points in time, the results tend to be more generalizable. Voluntary samples when you have people contact you.
