Equating Multidimensional Tests Under A Random Groups Design: A Comparison Of Various Equating Procedures, Eunjung Lee
Theses and Dissertations
The purpose of this research was to compare the equating performance of various equating procedures for the multidimensional tests. To examine the various equating procedures, simulated data sets were used that were generated based on a multidimensional item response theory (MIRT) framework. Various equating procedures were examined, including both unidimensional and the multidimensional equating procedures based on an IRT framework in addition to traditional equating procedures. Specifically, the performance of the following six equating procedures under the random groups design was compared: (1) unidimensional IRT observed score equating, (2) unidimensional IRT true score equating, (3) full MIRT observed score equating ...
