Madde Tepki Kuramının Farklı Uygulamalarından Elde Edilen Parametrelerin ve Model Uyumlarının Örneklem Büyüklüğü ve Test Uzunluğu Açısından Karşılaştırılması

Abstract

The purpose of this study is to identify NIRT, PIRT and MIRT across different sample sizes, test length and correlation between dimensions in a two dimensional simple structures. The aim is also to identify and compare and contrast the results of item parameters, model data fit for the items and model data fit for the test. Having analyzed the findings of the research, with the increase of sample sizes and test length, it is also found out that the model data fit for the test has increased as well. Different correlation between dimensions setup, model data fit for the test values has not formed a pattern. It can be stated that tests consisting of less items fit better to MIRT models. Model data fit for the items are calculated with quite low errors in NIRT. When the chi-square, infit and outfit values obtained for PIRT have been analyzed, it has been revealed that along with the increase of sample sizes and test length, all three coefficients exhibit better model fit.
