| Summary: | Grouping is a statistical procedure through which members of the same group are considered as a single unit of observation. There are methodological and inferential problems associated with various grouping procedures in various settings. This extensive paper focuses on making inferences about individuals when the analysis uses data that is grouped over individuals (for example, school means). The paper identifies five research contexts in which grouping is used, reviews the literature on grouping where only two variables are considered, and proposes a method for clarifying the problems involved in grouping. The method involves introduction of a new variable, a "grouping variable," into the analysis procedure. The grouping variable is essentially the value assigned to members of a group taken over all possible groups. The relationship of the grouping variable to the variables of interest forms the basis for a taxonomy of grouping situations which can then be assessed for certain statistical qualities. The paper discusses the logic and statistical basis for the method, considers the method in a variety of settings, and extends the logic to more complex cases. Empirical examples are presented and considerations for future developments are discussed. (JKS) |
