The Quiz and Item Analysis report includes two sections: Quiz Analysis and Item Analysis.
The Quiz Analysis includes statistics for overall assessment scores. These statistics include all students who have taken the assessment. The following statistics are available:

- Mean Elapsed Time [5]: displays average time to complete assessment
- Cronbach’s Alpha [6]: measures internal consistency of how closely related a set of items are as a group
In the Item Analysis section, you can view statistics for specific questions in an assessment. The following item analysis statistics are available:
- Difficulty Index [1]: shows how hard it is to answer the question correctly. Calculated by dividing the number of correct answers by the number of times the item was included in the assessment.
- Discrimination Index [2]: measures how well a question can tell the difference between students who do well on the exam and those who do not. Calculated by subtracting the bottom 27% of difficulty index scores from the top 27% of difficulty index scores.
- RPB (Point-Biserial Correlation Coefficient) [3]: measures the correlation between a given item and the total score.
- Mean Earned Score [4]: displays average point score.
