Methods for Identifying Biased Test Items 1KLCN Torrance KirbyThis book makes clear to researchers what item bias methods can (and cannot) do, how they work and how they should be interpreted. Advice is provided on the most useful methods for particular test situations. The authors explain the logic of each method from item response theory to nonparametric, categorical methods in terms of how differential item functioning (DIF) is defined by the method and how well the method can be expected to work.
