Kim, Seock-Ho; Cohen, Allan S.
Journal of Educational Measurement, v29 n1 p51-66 Spr 1992
Effects of the following methods for linking metrics on detection of differential item functioning (DIF) were compared: (1) test characteristic curve method (TCC); (2) weighted mean and sigma method; and (3) minimum chi-square method. With large samples, results were essentially the same. With small samples, TCC was most accurate. (SLD)
