The analysis module gives you detailed statistics that will help you to improve the quality of the items in your item bank. For example, it can be very useful to know that a certain distractor of a multiple-choice question is never selected by the participants. Then it is a very bad distractor, and you may want to replace it with a better one. Or it can be useful to know which answers the participants often typed in fill gaps items, so you can update the item and let it take other possible answers into account automatically.
Details of the item analysis
When you click through on an item in the analysis module, you will see the details of that item.
Currently, the following item types are supported:
- Multiple-choice items
- Multiple response items
- Fill gaps items
On the detail page of an item, you can see:
- The number of correct, incorrect, and partially correct answers, as well as the number of unanswered sessions
- The number of times each answer was selected, and whether or not it was correct
- The average time the participants spent on the item, as well as the shortest and longest session.
