What Information is Available?
- Basic Report Statistics: If any exam-takers have uploaded their exams, you can view the basic class report. Included in this report will be the mean, median, high, and low scores (at the top of the report).
Note: If your institution is participating in the Insights beta, the KR-20 metric will be replaced with Cronbach's Alpha.
- Question Details: Beneath the statistics, you will see the list of questions, their weight, the percentage of exam-takers who answered this question correctly, the point bi-serial score, and the percentage of lower 27% and upper 27% of exam-takers who answered the question correctly. The point bi-serial score represents the correlation between an exam-taker's performance on an individual question and on the exam as a whole.
- -1.00: Negative correlation
- 0: No correlation
- 1.00: Positive correlation
Notes: If your institution is participating in the Insights beta, the calculation of Point Bi-Serial will use sample standard deviation √(∑(xi - μ)2/(n-1)) instead of a population standard deviation √(∑(xi - μ)2/(n)).
Insights does not calculate the Point Bi-Serial correlation value for questions in a posting where partial credit was awarded to at least one student.
- Performance Stats and Scoring Adjustments: Select the pencil icon next to each question within this list to show the performance stats and Enterprise Portal: Adjust Questions & Score Assessments.
