A Snagit video capture that shows how to input the formula to determine the Discrimination Index for MC items. In practice, values of the discrimination index will seldom exceed .50 because of the differing shapes of item and total score distributions. ScorePak® classifies item discrimination as “good” if the index is above .30; “fair” if it is between .10 and.30; and “poor” if it is below .10.for item discrimination, acceptable values are 0.2 or higher; the closer to 1 the better in case the total Cronbach’s Alpha value is below the acceptable cut-off of 0.7 (mostly if an index has few items), the mean inter-item-correlation is an alternative measure to indicate acceptability; satisfactory range lies between 0.2 and 0.4Index of Difficulty Calculator. This is a common formula for calculating the Index of Difficulty (\(ID\)), but other formulas exist. $$$$
