SOCI 2150Y Chapter Notes - Chapter 6: Nonprobability Sampling, Quota Sampling, Sampling Frame
Document Summary
Chapter summary: social researchers must select observations that will allow them to generalize to people and events not observed. Often, this involves a selection of people to observe sampling: social researchers have developed several sampling techniques appropriate to different research situations. Informants should be selected in such a way that they provide a broad, diverse view of the group under study: probability sampling methods provide an excellent way of selecting representative samples from large, known populations. There will always be some degree of sampling error: a sampling frame is a list or quasi-list of the members of a population. It is the resource used in the selection of a sample. This method is more practical than simple random sampling and, with a few exceptions, is fundamentally equivalent: stratification is the process of grouping the members of a population into relatively homogenous strata before sampling.
