Scoring Multiple Choice Questions With Multiple Correct Answers

If a multiple choice question has only one correct answer, it is scored as you would expect. A point is given if you have answered the question correctly. Or if you set the question's "weight" to, for example, two points, then two points will be given if the answer is correct.

If a multiple choice question has more than one correct answer, the scoring is different. Each possible response is scored as if it were are true/false question. For example:

Q: My question
        		+ A
        		+ B
        		- C
        		- D

If you select A and B but not C or D, you will get all 4 possible points. If you select all four, you will 2 points: You get the points for A and B but not for C or D, because C and D were not supposed to be selected. If you select nothing at all, you would get two points, for C and D.

If you set a "weight" for this type of question, each response will be worth the "weight". So if you want the entire question to be worth 1 point if all options are selected correctly, you could set a weight of 0.25:

Q: My question
        		Weight: 0.25
        		+ A
        		+ B
        		- C
        		- D

This method of scoring allows partial credit for partially-correct responses without the possibility of negative scores.
