Analysis of multiple-choice items.

This paper deals with scoring and analysis of multiple-choice exam questions. Data may be read by an optical mark reader scanner or from a file created by a system editor and stored in a format convenient to be analysed by a specially designed program 'MCQ'. In addition the data file created can be linked with the package SPSSx for pertinent statistical methods or SPSS Graphics for illustration of score and item distributions. The MCQ program comprises: (1) scoring; (2) item analysis: difficulty and discrimination indices; (3) testing the goodness of alternatives attached to each question. The method is applicable to multiple-choice questions with 4.5 greater than 5; true/false and combined exam questions. The method should prove useful for instructors to build up a balanced discriminant questions bank.
