## Partial credit for multiple-answer questions.

If the question in a quiz has multiple answers, is there a way to give the student partial credit if he or she answers one correct answer but misses the other(s)?

Example:

4. What impact does the metaphor comparing the fire to a tower have in the excerpt?

a. It shows that the damage was minimal because it is taller rather than broader in scope.

(correct)  b. It helps the reader visualize the immenseness of the fire.

c. It references the first paragraphs to create an understanding of the meaning.

(correct)  d. It helps the reader feel as well as see the power in the fire.

.

If they choose one, could they get one of two points?

In multiple answer quizzes, partial scoring is implemented as following.

• You divide the number of points for the question by the number of correct responses. That's how much each selected response is worth.
• For every correct response that is selected, the student gets that many points. For every incorrect response that is selected, the student loses that many points.
• The student's grade may not go negative even if they mark more incorrect responses than they mark correct responses.
• Non-selected responses do not figure into the grading. The student doesn't get anything for not answering.

• Since there are 2 correct responses, each selected item is worth 1/2 of the possible points for the question.
• If they select one of the correct ones and select none of the incorrect ones, then they will get 1/2 of the possible points.
• If they select one of the correct ones and one of the incorrect ones, they will get 0 points since the missed one will cancel out the correct one.

In Legacy Quizzes, this is the only way to grade multiple answer questions. In New Quizzes, you can choose this method or an all-or-nothing approach.
