Refine the multiple choice questions tool with item analysis.

Assessment facilitates and improves learning outcomes. Multiple choice questions (MCQs) is one of the important tools in the assessment of learning outcomes and used most often due to its reliability and simplicity. It requires more time and effort of the educators in order to construct effective MCQs that serve its purpose. Work is only half done if we do not perform Item analysis after the completion of the MCQ test for assessment. Item analysis assesses the quality of each item (questions) in term of its difficulty level (Index of Difficulty), its ability to differentiate between high performers and low performers (Index of Discrimination) and how correctly the distractors are used in each item (Distractor Efficiency). The results of Item analysis helps to improve the strength of the MCQs, as good items can be retained whereas bad items are revised, replaced or removed. [ABSTRACT FROM AUTHOR]
