Document Summary
Sometimes, you may want to study a small subset of a larger population in which many members of the subset are easily identified. Systematic sampling: advantages of probability sampling: Probability samples are typically more representative than other types of samples. Probability theory permits us to estimate the accuracy or representativeness of samples: probability sampling is based on the use of random selection procedure. Elements: the unit of which a population is composed and which is selected in a sample. Population: the theoretically specified aggregation of the elements in a study. Study population: that aggregation of elements from which a sample is actually selected. Respondents: people who provide information about themselves, allowing the researcher to construct a composing picture of the group those respondents represent. Informant: someone well versed in the social phenomenon that you wish to study and who is willing to tell you what he or she knows.
