This paper reviews developments in nonparametric item response theory (NIRT). Historically, Mokken's (1971) item response theory (IRT) model and procedure of scale analysis have been the starting ...
We propose three latent scales within the framework of nonparametric item response theory for polytomously scored items . Latent scales are models that imply an invariant item ordering, meaning ...
model included 93.05% of respondents who fitted the model and it was selected for more detailed analysis of items and individual person’s reliability. The Yen’s Q3 statistic was used to test ...
the polytomous Rasch Model (Masters, 1982), which is an item response model for ordinal data where the item parameters (i.e., item difficulty) are measured on the same scale as the person parameters (i.e., person ...
was the model with the best data fit . Model fit was assessed with S-X2 item fit statistics for polytomous data, which quantify differences between observed and expected response frequencies under the GRM model ...
scores . While this summary score provides a quick representation of a person's ability, it disregards useful information on the item level. Objective: to use item response theory (IRT) methods to increase ...
