THE IMPACT OF A NUMBER OF CHOICES IN A TEST ON THE DIFFICULTY INDICATORS AND DISCRIMINATION

Abstract

This study aimed to investigate the relationship between a number of choices (alternatives) in a test, and the difficulty indicators and discrimination. A test of multiple choices on statistics students at the University of Jordan was used in this study. The test consisted of 30 items, and three forms (models). Also, a sample of 350 students was studied. The Statistical Package for Social Sciences (SPSS) software and Bilog-Mg were used for the analysis of the data based on the Two parameter models. Therefore, the findings of the present study uncovered a negative association between the number of choices and the difficulty indicator and discrimination.
