A questionnaire was constructed for the purpose of investigating various aspects of the career choices made by graduate students. The research was to determine the underlying structure of the questionnaire and to compare the capability of nonmetric multidimensional scaling (MDS) and linear factor analysis (FA) to reveal dimensions measured by the…

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…
