After the students are arranged with the highest overall scores at the top, count the number of students in the upper and lower group who got each item correct. For Question #1, there were 4 students in the top half who got it correct and 4 students in the bottom half.
Determine the Difficulty Index by dividing the number who got it correct by the total number of students. For Question #1, this would be 8/10 or p=.80.
Determine the Discrimination Index by subtracting the number of students in the lower group who got the item correct from the number of students in the upper group who got the item correct. Then, divide by the number of students in each group [in this case, there are five in each group]. For Question #1, that means you would subtract 4 from 4, and divide by 5, which results in a Discrimination Index of 0.
