Journal Title: Medpulse International Journal of Community Medicine - Year 2017, Vol 3, Issue 2
Abstract
Background: Item analysis is an important component in the assessment of students and the examination program. The analysis is done by calculation of difficulty index and discrimination index. The conventional method which divides the students in 3 groups is tedious and has some technical difficulties. To overcome them, we have attempted to suggest simplified method. Objective: To assess the simplified method of item analysis against conventional method. Material and Methods: The present cross sectional study was conducted at Government Medical College, Latur in November 2015. Conventional method divides the students in 3 groups but we have divided them in only 2 groups. Item analysis was done by both conventional and simplified method for 10 MCQs which were answered by students of 1st semester. The standard error of difference between proportions was calculated to test the difference in two methods. Results: The difficulty index and discrimination index calculated by conventional and new simplified method were statistically comparable. But the advantage of new method is that, it is easier, simpler and has few technical difficulties. Conclusion: As new method for item analysis is shorter, simpler and statistically comparable with conventional method, it can be a good substitute for traditional method.
