The Mean or Average Deviation is a Minimum when taken from the Median

The structure of students’ responses on a semantic differential instrument to certain facets of their university was analyzed by Tucker’s three-mode factor analytic procedure. Factors were identified and named for the R, P, Q and core matrices. Tucker’s procedure offers the investigator additional information in interpreting such response data. The additional information obtained from Tucker’s procedure over classical two-mode procedures, particularly the core box of interdependencies, was helpful in interpreting the semantic differential data.
