Peer reviewedCohen, Allan S.; Kim, Seock-Ho – Applied Psychological Measurement, 1993
The effectiveness of two statistical tests of the area between item response functions (exact signed area and exact unsigned area) estimated in different samples, a measure of differential item functioning (DIF), was compared with Lord's chi square. Lord's chi square was found the most effective in determining DIF. (SLD)
