Test item is acceptable which its faculty index /difficulty level ranges from?
 A 30% B 70 % C 30-70 % D None
Explanation:

Detailed explanation-1: -Difficulty index is the proportion or probability that candidates, or students, will answer a test item correctly. Generally, more difficult items have a lower percentage, or P-value.

Detailed explanation-2: -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.

Detailed explanation-3: -If a difficulty index is less than 0.30, then the question would be considered very difficult. If the difficulty index is greater than 0.95, then the question would be considered very easy.

Detailed explanation-4: -It was calculated using the formula DIF I or P = (H + L) × 100/N, where H = number of students answering the item correctly in the high achieving group, L = number of students answering the item correctly in the low achieving group and N = total number of students in the two groups (including non-responders).
