Analytics are an easy way to get insight into the results of an assignment. Analytics allows the instructor to see details about grades, but also about questions, objectives, and graders if the assignment is graded online.
- Sign in to Ans
- Click on your course or use the search bar in the Courses-section.
- Click on your assignment or use the search bar.
- Click Insights in the menu at the top.
The Overview-page is shown and a couple of insights are given:
- The number of participants.
- The Cronbach's alpha is shown. The Cronbach's alpha measures the reliability of the assignment and tests this by checking if the grade of students changes a lot if you delete a question.
- For bubblesheet assignments only: the KR 20 is shown. The KR 20 indicates the reliability of a test. The KR 20 has a value between 0 and 1. A high value means a high reliability.
- The pass rate.
- The minimum, average and maximum grade are shown.
- The duration of the test.
Note: Most data shown in the Insights environment are not reliable for small amounts of data (students). Beware of this when making conclusions based on Analytics.
