Determined the extent to which direct judgments of similarity by supervisors and incumbents could provide the same job classification results as a more elaborate job analysis procedure. Results using hierarchical cluster analysis and multidimensional scaling analysis revealed that the global judgments and task-oriented data led to identical…

Ranking and rating methods of making direct judgments of pairwise similarity are compared. Three dimensional configurations of seven objects are derived under both judgment methods across two equivalent groups of 59 university students. Using Cliff's orthogonal rotation method of multidimensional matching, comparisons are made between methods…

A study was conducted to determine the dimensions underlying the items on a course-instructor survey instrument currently in use to measure graduate student ratings of instruction (attached). Both factor analysis and multidimensional scaling methods were used to analyze the response data, so that the results of each could be evluated, and the two…
