A Closer Look at the Accuracy of Alternative Data-Collection Methods for Multidimensional Scaling

Subkoviak, Michael; Roecks, Alan L.

Journal of Educational Measurement, 13, 4, 309-17, Win 76

Three different methods of data collection were examined in which subjects judged proximity between object pairs. Significant differences in accuracy were found among the three methods, presumably due to differences in the extent to which subjects are able to describe their perceptions under the various methods.
