Thin versus Thick Matching in the Mantel-Haenszel Procedure for Detecting DIF.

Donoghue, John R.; Allen, Nancy L.

Journal of Educational Statistics, v18 n2 p131-54 Sum 1993

Forming the matching variable for the Mantel-Haenszel differential item functioning (DIF) procedure through use of the total score as the matching variable (thin) and forming the matching variable by pooling total score levels (thick) were compared in a Monte Carlo study. Reasons thick matching is superior are discussed. (SLD)
