Assessing Differential Item Functioning among Multiple Groups: A Comparison of Three Mantel-Haenszel Procedures.
Penfield, Randall D.
Applied Measurement in Education, v14 n3 p235-59 2001
Compared the performance of three methods of assessing differential item functioning (DIF) across demographic groups, using: (1) the Mantel-Haenszel chi-square statistic with no adjustment to the alpha level; (2) the Mantel-Haenszel statistic with a Bonferroni adjusted alpha level; and (3) the generalized Mantel-Haenszel statistic. Simulation results show that the generalized approach is the most appropriate in terms of Type I error and power. (SLD)
