The Effect of Individual Differences in Abilities on Interpreting the Dimensionality of Multiple-Choice Tests.
Hogan, M. J.; And Others
The problem of interpreting the dimensionality underlying binary test data is addressed. Medical school students were tested on both achievement and aptitude measures. The person-by-test (aptitude) interaction matrix was factor-analyzed to identify patterns of individual differences. The resultant groups of similar patterns were used as the criteria in a discriminant function analysis where the discriminator variables are the achievement test items. The results strongly indicate that performance on the achievement test can be partially explained by the differential pattern of performance on the aptitude tests. (Author)
