Detailed explanation-1: -The discrimination index is less than 0.10, which indicates that there was little difference in how higher-scoring and lower-scoring students answered the question.
Detailed explanation-2: -Item Difficulty Index It can range between 0.0 and 1.0, with a higher value indicating that a greater proportion of examinees responded to the item correctly, and it was thus an easier item.
Detailed explanation-3: -If an item has a discrimination index of 0, it indicates it is not discriminating at all – i.e. the same number of people in the higher group got it correct as in the lower group.
Detailed explanation-4: -Calculating Item Difficulty Count the total number of students answering each item correctly. For each item, divide the number answering correctly by the total number of students. This gives you the proportion of students who answered each item correctly. This figure is called the item’s difficulty level.
