Abstract

This study aims to evaluate the empirical quality of multiple-choice test instruments for Mathematics subjects in Statistics material at the high school (SMA) level. The analyzed instrument consisted of 20 multiple-choice questions that were tested on 25 students in class X of SMA PGRI Mnelalete. The research method used is quantitative descriptive with a Classical Test Theory approach. Data analysis was carried out with the help of Microsoft Excel software to calculate the parameters of the validity of the question item, the reliability of the instrument, the level of difficulty, and the differentiating power of the question. The results of the analysis showed that the reliability coefficient of the test was 0.84 (high category). Cumulatively, of the 20 questions analyzed, there were 14 questions (70%) that met the good quality criteria so that they were immediately accepted in the question bank, 4 questions (20%) required revisions to sentence construction or distractor functions, and 2 questions (10%) were discarded because they had insignificant discriminating power. Periodic evaluation of this spreadsheet-based empirical assessment instrument has proven to be effective in helping teachers in mapping the feasibility of measuring student learning outcomes.
