Generalization of Findings From Single Case Studies.
Kennedy, Mary M.
Although single case studies might be useful to evaluators for a variety of purposes, there are no generally accepted ways for drawing inferences about the generality of findings from a case study. Single case studies are defined in this paper as either studies of single events, or disaggregated studies of multiple events. The data may be qualitative or quantitative, and may be derived from controlled experiments or from observation. There are two spans to the bridge of inference. The statistical span connects the experimental sample to a popluation just like that sample. The second span connects the population to a group judged to be sufficiently similar. In case law or in clinical practice, the judgment of sufficient similarity --that is, the judgment of the appropriateness of the generalization--is made by the user. This application of single case data may also be appropriate in educational evaluation. (CTM)
