How do I fix a wrong answer in my quiz when my students have already completed the quiz?
There are several ways to deal with "bad" questions in a quiz.
Change the grade for the bad question to 0 in the quiz.
Edit the question, changing what you will accept as a correct answer, then regrading the exam. Remember when changing a question that the next time it is used it will be as it was in the last edit. Also, regrading will only affect one quiz at a time.
You can edit the question to explain the situation to the student and then you can set the grade for the question to zero. After you make such changes you should regrade the quiz by clicking on the Results tab and then the Regrade tab. This will change the grade for all students who have taken the quiz so far. Remember, if the question is used by another quiz, your "explanation" will appear as part of that quiz.
You can change the grade for the bad question and then move or delete the question from your question category. The question will still appear on the quiz. Some places do not like to delete any question, but will move them to a "dead" or "bad" question category.
- When you discover a bad question in your quiz, it may affect the question bank. Remember that a final might be made up of a certain number of random questions drawn from different question categories, the same categories used in a smaller subject quiz. It can be very important do something about bad or invalid questions in a question category when the categories are used in other places.
