The Subject-Item Interaction in Itemmetric Research

Kuncel, Ruth Boutin

Educational and Psychological Measurement, 37, 3, 665-78, Aut 77

The interaction of subjects with test items is investigated. It is suggested that psychometricians rely too heavily on inferences about the nature of the interaction. An approach to data analysis is proposed which is more directly related to this interaction. (JKS)
