This study aims to analyze the differential bundle functioning in multidimensional tests with a specific purpose to detect this effect through differentiating the location of the item with DIF in the test, the correlation between the dimensions, the sample size, and the ratio of reference to focal group size. The first 10 items of the test that is…

A multidimensional unfolding technique that is not prone to degenerate solutions and is based on multidimensional scaling of a complete data matrix is proposed: distance information about the unfolding data and about the distances both among judges and among objects is included in the complete matrix. The latter information is derived from the…

Describes the use of ALSCAL, a computer program for multidimensional scaling, to map enrollment in 49 electives at Drexel University's College of Information Studies during two time periods. The results for this department are presented, and the explanatory power of this evaluation technique for any curriculum is discussed. (6 references) (CLB)
