You can create a question that has multiple answers in it.

Notes:

• If you need to edit a Multiple Answers question after publishing the quiz, you can use quiz regrade to edit quiz questions and tell Canvas to update grades for students who have already taken the quiz. However, this option only works for regrading existing questions, not deleting questions completely.
• To calculate scores for Multiple Answers quiz questions, Canvas divides the total points possible by the amount of correct answers for that question. This amount is awarded for every correct answer selected and deducted for every incorrect answer selected. No points are awarded or deducted for correct or incorrect answers that are not selected. For example, an instructor may create a Multiple Answer quiz question with 9 points possible that includes three correct choices and two incorrect choices. If a student selects two correct answers and one incorrect answer, they would be awarded 3 total points for that question. This would be calculated by awarding 3 points (9 total points divided by 3 correct answers) for each correct answer and subtracting 3 points for the incorrect answer.
