Irt equating
Webway? Indeed, IRT equating has some important advantages. IRT offers tremendous flexibility in choosing a data collection plan for equating the scores. If the necessary data on the … Webdesign are also compared to "no equating.11 In "no equating," the raw-to- scaled score conversion table is constructed under the assumption that the conversion table on a new form is identical to that for a given old form. Equipercentile and three-parameter logistic item response theory (IRT) equating methods are compared for both designs.
