Wu, Yi-Fang – ProQuest LLC, 2015
Item response theory (IRT) uses a family of statistical models for estimating stable characteristics of items and examinees and defining how these characteristics interact in describing item and test performance. With a focus on the three-parameter logistic IRT (Birnbaum, 1968; Lord, 1980) model, the current study examines the accuracy and…

Wang, Zhen; Yao, Lihua – ETS Research Report Series, 2013
The current study used simulated data to investigate the properties of a newly proposed method (Yao's rater model) for modeling rater severity and its distribution under different conditions. Our study examined the effects of rater severity, distributions of rater severity, the difference between item response theory (IRT) models with rater effect…

White, Karl R.; Carcelli, Larry – 1982
The effect on children's test scores of different item formats used in standardized mathematics achievement tests was investigated. In a Utah school, 40 second grade students completed a mathematics computation test using eight different formats derived from five standardized achievement tests. Identical content, taken from the most frequently…
