Application of a Method of Estimating DIF for Polytomous Test Items
Abstract
In this paper, a method for studying DIF is demonstrated that can used with either dichotomous or polytomous items. The method is shown to be valid for data that follow a partial credit IRT model. It is also shown that logistic regression gives results equivalent to those of the proposed method. In a simulation study, positively biased type 1 error rates of the method are shown to be in accord with results from previous studies; however, the size of the bias in the log odds is moderate. Finally, it is demonstrated how these statistics can be used to study DIF variability with the method of Longford, Holland, & Thayer (1993) .

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.
