Document Summary
Gives the ability to generalize (quantitative research) Sampling: the process of selecting a subset of cases in order to draw conclusions about the entire set. Key terms: target population/ defined study population. The populations to which researchers would like to generalize their results. Unit of analysis : the entity about whom or which the researcher gather information (individuals, groups, social artifacts: sampling frame. An operational definition of the population that provides the basis for drawing a sample. A list of cases from which a sample may be selected. Example: phone book, student registry: sample (individual cases) A subset of people selected for a study: coverage error. A mismatch between the target population and sampling frame. Example: phone book: using a phone book create a coverage error as not everyone is listed in this sampling frame. Duplication (overcount: sample the same individual twice) Technical problem (e. x. no access to the internet) Attrition: sampling error- statistics vs. parameters.
