DIF DETECTION AND DESCRIPTION: MANTEL‐HAENSZEL AND STANDARDIZATION1,2

Open access
Dorans, Neil J., Holland, Paul W.·1992·ETS Research Report Series

Abstract

At the Educational Testing Service, the Mantel‐Haenszel procedure is used for differential item functioning (DIF) detection and the standardization procedure is used to describe DIF. This report describes these procedures. First, an important distinction is made between DIF and Impact, pointing the need to compare the comparable. Then, these two contingency table DIF procedures are described in some detail, first in terms of their own origins as DIF procedures, and then from a common framework that points out similarities and differences. The relationship between the Mantel‐Haenszel procedure and IRT models in general and the Rasch model, in particular, is discussed. The utility of the standardization approach for assessing differential distractor functioning is described. Several issues in applied DIF analyses are discussed including inclusion of the studied item in the matching variable, and refinement of the matching variable. Future research topics dealing with the matching variable, the studied variable and the group variable are also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
