Nonmetric Multidimensional Scaling: An Evaluation of Three Data Collection Methods.
Subkoviak, Michael J.; Roecks, Alan L.
The present study examined three different methods of data collection in which subjects judged proximity between object pairs. One method required subjects to partition objects into homogeneous subsets; the second entailed rating object pairs on a similarity-dissimilarity continuum; and the third involved comparing inter-object proximities to a fixed standard. The three types of proximities were analyzed by the nonmetric multidimensional scaling procedure, and subsequent multidimensional representations were compared for accuracy to a criterion or "true" multidimensional configuration of the same objects generated by the same subjects. Considerable differences in accuracy were found among the methods. (Author)
