The Exploration Of Non-Linear Model was Reviewed Based On The Length Of The Test

Abstract

The purpose of this study is to explore the resulting dichotomous nonlinear data model analysis on a multidimensional three-parameter logistic model. This study used a sample size of 1500 with grain lengths of 20 items, 30 items, and 40 items. The instrument used was the 2015 DKI Jakarta National Examination Question. The data used were analyzed using testfact software. The results showed that the use of the nonlinear model in the multidimensional three-parameter logistic model was very good, because the participants' low ability in other dimensions would answer correctly in other dimensions.
