Robustness Domain Score of the Change in Test of Dimensionality and the Correlation between Dimensions and Ability Distribution: A Generated Data

Abstract | الملخص

This study aimed at investigateing the effects of the test of dimensionality Domain Score calibration. Also. It investigated the effects of the correlation between dimensions (0.2, 0.9) and ability distribution (Normal, Uniform) on Domain Score calibration. To achieve the purpose of the study, responses for four groups (1000 examinee for each group) were generated on seven tests (3 unidimensional, 3 bidimensional, and 1multidimensional). The results indicate that there were differences in Domain score calibration due to the test of dimensionality (unidimensional, bidimensional and multidimensional) and ability distribution. Results showed no differences due to correlation between dimensions.
