Sheel Thorat, Madhur Gupta, Madhura Wasnik

Abstract


MCQ are used more often to assess students of different educational fields for their objectivity. Making a fair analysis of students performance can be a challenging job. Item analysis of MCQ`s is one of the suggested method for analysis. 60 MCQS were randomly selected which were given to 1st M.B.B.S. students in term and prelim exam. Item analysis was done by calculating difficulty index [DIF] and Discrimination index [DI]. In the result we concluded that out of 60, 9MCQS were in very difficult value, 28 in easy and 22 in acceptable. 16 MCQS were in 0.2 discrimination and 46 were in less than .2 discrimination index. So these MCQ`s were fairly distributed in nature.

Keywords: MCQs, Biochemistry, Item analysis.
