RANDOMIZATION OF MULTIPLE CHOICE QUESTIONS FOR COMPUTER ASSISTED TEST (CAT) IN STUDENT SELECTION

Abstract

Computer Assisted Test (CAT) is a computer application designed to help selection process, particularly to examine multiple choice questions. This application requires random questions and answer choices derived from a question bank. One of the random number generator is computational algorithms, or the so-called pseudo-random number generators. In this research, the model and randomized algorithm had been developed to generate the initial development of Computer Assisted Test. Linear congruential was used as the method to generate random number. One-sample Chi-Square test was applied to test the model and algorithm for randomness of question items. The statistic test result show χ2 = 206 and critical values χ20.05,199 = 232.19, while the number of answer choices for randomness tests statistically obtained χ2= 4.0 and the critical value χ20.05,8 = 15:51. From both the results of these tests concluded that the randomness of questions and answer choices produce a number of questions and answer choices that number has an equal chance of being selected.
