المقارنة بين النظرية الكلاسيكية و النموذج الثلاثي البارامتر في معالجة أثر التخمين عند تقدير إحصائيات الأفراد و المفردات في اختبار "اختيار من متعدد"

Abstract EN

The present research aims to compare Classical lest Theory (CTT) to Three Parameter logistic Model (3PLM) in processing the effect of guessing when estimating item statistics (difficult, and discrimination parameter) and person statistics (represented at the ability of senior students and general diploma students in the Faculty of Education-Minia University) in multiple-choice achievement test in psychological measurement course.

The difference between these statistics estimated with CTT before the correction of guessing, CTT after the correction of guessing and 3PLM were explored.

The findings indicated that there was no significant difference between CTT after the correction of guessing statistics and CTT before the correction of guessing statistics but there was a significant difference between 3PLM statistics and CTT before the correction of guessing statistics.

The results furthermore demonstrated that there was a significant difference between 3PLM statistics and CTT methods in processing the effect of guessing when estimating item/person statistics for multiple-choice test.
