Difficulty and
Discrimination
Indexes Displays the difficulty index and the discrimination index for each individual
question item during a single session or assessment.
Formula for the Difficulty Index:
• D = Difficulty Index
• NH = Number of correct responses in the top 27%* (participants who
responded with the most number of correct answers during the session)
• NL = Number of correct responses in lower 27%* (participants who
responded with the least number of correct answers during the session)
• T = Number of total responses in the top and lower groups
• D = (NH + NL) / T
Formula for the Discrimination Index:
• D = Discrimination Index
• NH = Number of correct responses in the top 27%* (participants who
responded with the most number of correct answers during the session)
• NL = Number of correct responses in lower 27%* (participants who
responded with the least number of correct answers during the session)
• T = Number of total responses in the top and lower groups
• D = (NH - NL) / .5(T)
*If there is a tie determining the top and lower percentiles, the participants
will be sorted based on the Device ID of the response device.

responses to each of the presentation questions.
