The Effects of Small Sample Size on Identifying Polytomous DIF Using the Liu–Agresti Estimator of the Cumulative Common Odds Ratio
This study is an evaluation of the behavior of the Liu—Agresti estimator of the cumulative common odds ratio when identifying differential item functioning (DIF) with polytomously scored test items using small samples. The Liu—Agresti estimator has been proposed by Penfield and Algina as a promising approach for the study of polytomous DIF but no simulation study focusing on small samples has analyzed this estimator regarding effect size, Type I …
A Comparison of Approaches for Improving the Reliability of Objective Level Scores
This study is an evaluation of the psychometric issues associated with estimating objective level scores, often referred to as ‘‘subscores.’’ The article begins by introducing the concepts of reliability and validity for subscores from statewide achievement tests. These issues are discussed with reference to popular scaling techniques, classical test theory, and item response theory. Methods for increasing the reliability of subscore estimates th…
