Extended Mantel-Haenszel Procedure for DIF Detection : A Note on Its Implementation in ACER ConQuest
'Pacific Rim Objective Measurement Symposium (PROMS) 2012 Conference Proceeding

Abstract
Many methods have been developed for studying Differential Item Functioning (DIF). An approach developed by Holland and Thayer (1988) adapted the Mantel-Haenszel (MH) statistic (Mantel and Haenszel 1959). The author of this chapter has implemented MH procedure and its extension in an experimental version of ACER ConQuest which can handle DIF analysis for multiple focal groups and polytomous items. This chapter compares the extended MH procedure in DIF detection to the standardized item difficulty difference method based on the Rasch estimates for both dichotomous and polytomous items. The use of MH method in DIF analysis with multiple focal groups is illustrated.
