varimax rotation

a statistical procedure applied within factor analysis and principal components analysis to simplify solutions and enhance interpretation of the results. It is a type of orthogonal rotation intended to make each factor have a small number of large factor loadings and a large number of zero (or small) factor loadings. Thus, following a varimax rotation, each original variable tends to be associated with a small number of factors, and each factor represents only a small number of variables. See factor rotation.

multiple comparison test

any of various statistical procedures used to follow up on a significant result from an analysis of variance by determining which groups in particular differ in their mean values. Examples include Duncan’s multiple range test, the Fisher least significant difference test, the REGWQ test, the Scheffé test, and Tukey’s honestly significant difference test.
