An Application of Person-fit Indices to EPQ
摘要
Abstract
Objective: Person-fit indices were computed on EPQ. This study was to investigate the cause of misfit and the influence of the inclusion of misfitting persons in parameter estimates. Methods: lz and Guttman error were used to investigate the misfit. MD. RMSD indices and ICC method was used to evaluate the effect of deletion of mifitting persons. Results: ①1z＜-1.65 was found in 3.44％ of the examinees, and 1z was correlated -0.838 with Guttman error; ②There were 32 in 50 most misfitting persons ranked in adjacent numbers; ③It was found that person parameters changed little after deleting misfitting persons. However, the high α high β items and the high α low β items changed a lot. Conclusion: A group of aberrant response persons in the same testing environment were found out by person-fit indices in group test. The presence of misfitting person cannot influence person parameters much, but resulted in underestimating discrimination parameters, and then influenced the bias in estimation of higher or lower threshold parameters.关键词
