Analisis Aitem Subtes In 1 (Number Series) pada Usu General Reasoning Test (U-Grt)

Abstract

Item analysis is important in the development of measuring tools. The purpose of this study was to analyze the IN 1 subtest item on the U-GRT in terms of reliability coefficient, validity coefficient, and item difficulty index. Primary data was obtained by giving tests to 49 samples with an age range of 15-25 years. Based on the results of the analysis, the reliability coefficient using the value of person reliability is 0.652, meaning that the reliability of this subtest is weak. The validity coefficient using the MNSQ infit value and the MNSQ outfit has a value from the range of 0.858 - 1.226, meaning that the validity is good. The item measure value moves from -1.222 - 2.586, meaning that the item difficulty index is high. The results of this study indicate that an item evaluation must be carried out by means of re-testing because it has not reached a satisfactory level due to weak reliability and a high item difficulty index.
