Comprehensive Analysis of Test Item Variance
McQuitty, Louis L.
Educational and Psychological Measurement, 36, 1, 51-84, Spr 76
A method of analysis is developed which accounts for whatever variance is present in the responses to test items, additive, configural or the two combined. The method is applied to successive column matrices which report frequencies or endorsements by categories of subjects to answer alternative sets of test items. Approaches are included which identify the kind of variance isolated. (RC)
