Detailed explanation-1: -0. “1” indicates the answer was correct; “0” indicates it was incorrect. Follow these steps to determine the Difficulty Index and the Discrimination Index.
Detailed explanation-2: -Difficulty index is defined as the percentage of those candidates recording either a true or false response for a particular branch in a multiple true–false response MCQ who gave the correct response.
Detailed explanation-3: -Maximum discrimination is usually found at the 50 per cent level of difficulty. 0.00 – 0.20 = very difficult 0.21 – 0.80 = moderately difficult 0.81 – 1.00 = very easy.
Detailed explanation-4: -So for example, if you have an item difficulty of 0.95, it doesn’t mean it’s extremely difficult. It means it’s extremely easy because that 0.95 represents the fact that 95% of the students got it correct.
