- Abstract
This paper reports the relationship between the difficulty index and the discrimination index of one-best answer type multiple-choice questions (MCQ's) in an anatomy paper for the students of year I of an undergraduate medical program. We included in this study the MCQ paper from the two partial examination of academic year 2008/2009. There were 52 students who attended the 2 partial examination in year 2008/2009. This examination covered anatomy of cardiovascular and respiratory systems. There was a wide distribution of item difficulty indices in all the MCQ papers analyzed. Mean difficulty index was 50.84 ± 17.30 with range 21.4 - 85.7 and mean discrimination index was 0.40 ± 0.21 with range -0.07 - 0.71. On average, 13.3 % of the MCQ items in anatomy paper were "very easy" (difficulty index > 70), while 13.3 were „very difficult” (difficulty index < 30). About 75 % of these very easy/difficult items had "very poor" or even negative discrimination. Our finding indicate that 73.4 % of studied MCQ's have recommended difficulty index and 76.7 % of questions have good or excellent discrimination index. 26.6 % of analyzed questions are too easy or too difficult and 13.3 % of questions have poor discrimination.
