Item Response Theory
Item Response Theory describes the application of mathematical models to data from questionnaires and tests as a basis for measuring abilities, attitudes, or other variables. It is used for statistical analysis and development of assessments, often for high stakes tests such as the Graduate Record Examination.
Group Differences Based on Irt Scores
In this study, effect sizes based on simulated groups were compared for the one-parameter and three-parameter logistic IRT models. Data were generated based on a three-parameter model, and item estimates were obtained from the simulated data based on both the one-parameter and three-parameter models. Abilities were estimated using both maximum likelihood and expected a posterior methods. The data fit the three-parameter model much better, but the…
