    Subgroup analysis refers to repeating the analysis of a study within subgroups of subjects defined by a subgrouping variable. For example: ...

  3. Subgroup - Wikipedia

    en.wikipedia.org/wiki/Subgroup

    A proper subgroup of a group G is a subgroup H which is a proper subset of G (that is, H ≠ G). This is often represented notationally by H < G, read as "H is a proper subgroup of G". Some authors also exclude the trivial group from being proper (that is, H ≠ {e} ). [2] [3] If H is a subgroup of G, then G is sometimes called an overgroup of H.

  4. Group dynamics - Wikipedia

    en.wikipedia.org/wiki/Group_dynamics

    The history of group dynamics (or group processes) [2] has a consistent, underlying premise: "the whole is greater than the sum of its parts." A social group is an entity that has qualities which cannot be understood just by studying the individuals that make up the group.

  7. Subgroup series - Wikipedia

    en.wikipedia.org/wiki/Subgroup_series

    Subgroup series can simplify the study of a group to the study of simpler subgroups and their relations, and several subgroup series can be invariantly defined and are important invariants of groups. A subgroup series is used in the subgroup method. Subgroup series are a special example of the use of filtrations in abstract algebra.

  8. Vignette (psychology) - Wikipedia

    en.wikipedia.org/wiki/Vignette_(psychology)

    Subgroups of respondents receive different sets of event sentences, and the subgroup data are pooled for final analyses. Vignettes enable controlled studies of mental processes that would be difficult or impossible to study through observation or classical experiments.

  9. Group analysis - Wikipedia

    en.wikipedia.org/wiki/Group_analysis

    Group analysis combines psychoanalytic insights with an understanding of social and interpersonal functioning. There is an interest, in group analysis, on the relationship between the individual group member and the rest of the group resulting in a strengthening of both, and a better integration of the individual with his or her community ...
