Combined with the actual case, RMFRM and MFRM
are compared, which illustrate that RMFRM can better reflect user browsing habits.
The MFRM model is an extension of the Partial Credit Model for polytomous items in which a test taker's performance is scored using one or more rubrics, each of which is composed of a set of ordered categories.
Since what we want to determine is whether the raters differ in the manner in which they apply the rubrics, this formulation of the MFRM model allows us to investigate whether that is the case.
The analyses with the MFRM model were run using the FACETS computer program (Linacre, 2009).
Although greater emphasis has been placed on the evaluation of differences in rater severity, also of interest in this paper is that we employed the MFRM model to measure the facet elements that affect the grading of the written expression tasks on the exam.
MFRM es una extension del Modelo de Credito Parcial para items politomicos en los que la ejecucion de la persona es calificada mediante un conjunto de categorias ordenadas.
En esta formulacion del MFRM se asume que los pasos ([F.
Los analisis con el modelo MFRM pueden ser realizados con el programa FACETS (Linacre, 2009).
The bias-interaction function in the MFRM was used to (1) investigate the activities in relation to the user ability and (2) investigate the sex and prosthetic side in relation to the activities.
The MFRM also reported a t statistic that tested the hypothesis that there was no significant interaction other than measurement error.
