Additional setup options

Scoring type

Choose your Scoring Type for the question after you have placed the correct responses into each response box.

Select Exact Match to require that students correctly respond to all choices. This option allocates 100% of the possible points for correctly responding to each response box and zero points if one or more responses are incorrect.
Select Partial Match to score each correct response individually. The total question score is divided across responses.

Partial match

If the Scoring Type is set to Partial Match, the formula for scoring the question is:
(value of the percentage ÷ the number of response boxes) × the number of selected correct responses = partial match value

The partial match value does not represent the number of points the response will receive, but the percentage of the total possible points.
The calculation always uses 100% from the main correct answer—not the alternate answers.

Partial match example
If there are four possible correct responses, and a student has three correct responses and one incorrect response, the value produced by the formula would be 75%.
(100 ÷ 4) × 3 = 75

If the question is worth 10 points, the student would receive 7.5 points, because 75% of 10 is 7.5. To penalize the student for the incorrect responses, refer to the Penalty score information.

From Instructor stimulus, enter extra instructions or information related to the question. This is intended for review only by the instructor or author. The content is displayed to instructors from Preview Question.

Penalty score

When using Partial Match, you can subtract points for incorrect selections.

Enter 0 for the Penalty Score to ignore wrong answers.
Enter 100 to weigh incorrect answers the same as correct ones.

The formula for scoring a question with a penalty score is:
partial match value - [(penalty ÷ the number of response boxes) × the number of selected incorrect responses]

The penalty formula, like the partial match formula, produces a relative percentage, not a point value.
The penalty is applied by dividing the penalty score by the total number of response boxes to determine the percentage deducted per incorrect response.

Penalty score example

If you were to take the previous example and add a Penalty Score of 20, the value produced by the penalty would be 70%.
75 - [(20 ÷ 4) × 1] = 70

Again, if the question is worth 10 points, the student would receive 70% of 10, which is 7.
