Working vocabulary for this monograph. -- Description of DIF: Formal definition of DIF. DIF: Uniform or not -- Statistical facets of DIF: Not mean (average) difference. Error in measurement. Differences are systematic. Matching on ability or proficiency. Conditioning criterion: internal versus external.

Outdated ANOVA methods -- Mantel-Haenszel procedure: CHi-Square contingency table. M-H odds ratio -- Nonparametric methods: DIF with SIBTEST. Dorans's standardization -- IRT-based methods: IRT framework. Item response curves. The one-parameter model. The two-parameter model. The three-parameter model. DIF methods based on IRT. Differences in item parameters. Likelihood ratio test. Area measures. IRT approaches for detecting DIF in polytomous items -- Logistic regression: The logistic regression DIF expression. Example of DIF by logistic regression -- Specialized scored items. Computer-based testing. Computer-adaptive testing. Translated tests -- Future Directions: Validity argument. Null hypothesis testing. Statistical modeling (HLM and Other). Equivalence testing. DFIT and CDIF testing |
