Simultaneous DIF Amplification and Cancellation: Shealy-Stout's Test for DIF.

Nandakumar, Ratna

Journal of Educational Measurement, v30 n4 p293-311 Win 1993

The phenomenon of simultaneous differential item functioning (DIF) amplification and cancellation and the role of the SIBTEST approach in detecting DIF are investigated with a variety of simulated test data. The effectiveness of SIBTEST is supported, and the implications of DIF amplification and cancellation are discussed. (SLD)
