Learn@UW - Weighting of Answers in Quiz Questions
For some types of quiz questions, numerical weights are specified on a scale of 0 (no credit) to 100 (full credit) for possible responses, in order to automatically grade the questions.

The weights must be entered as numerical values into a text box.
Weights must be numerical values between 0 and 100, inclusive. Up to 2 decimal places are allowed. Each weight represents percent of full credit. Be careful not to confuse the weight with the absolute number of points that should be awarded.
In addition, the weights should be specified as follows depending on the question type:
True/False, Multiple Choice, Short Answer
A correct (or best) answer should have a weight of 100 so that full credit is awarded for selecting that answer.
For example, suppose a multiple choice question has 5 possible answers. The correct answer is (a), but you also want to give 50% credit for answer (c) and 30% credit for answer (e). You would assign weights of 100 for (a), 50 for (c), 30 for (e), and 0 for the remaining choices.
Fill in the Blanks
The weights should sum to 100 so that full credit is awarded for supplying all correct answers.
NOTE: If the sum of the weights exceeds 100, this condition is not trapped and supplying all correct answers will result in being awarded more points than the question is worth.
For example, if there are 3 blanks to fill in the question but the third blank is deemed 'less important' than the others, you could assign weights of 40 to the first two blanks and 20 to the third blank.
Multiple Short Answer
For most questions of this type, the weights should all be specified as 100 divided by the number of answers to be supplied (input boxes). It may be necessary to round to two decimal places (for example, specify weights of 33.33 or 33.34 if there are three answers to be supplied). This will ensure that full credit is awarded when selecting any correct combination in cases where the number of answers to be supplied is fewer than the number of possible correct answers. In the case of a "name all" question where the number of answers to be supplied is equal to the number of possible correct answers, the weights should sum to 100 but may vary.
NOTE: If the sum of weights for a possible set of correct answers exceeds 100, this condition is not trapped and answering the question correctly may result in being awarded more points than the question is worth.
For example, suppose the question begins with "Name four of the five ...". You should specify a weight of 25 for all answers. If a question begins with "Name all five ...", you would usually specify a weight of 20 for all answers, but could vary the weights as long as they sum to 100.
The illustrations below provide examples showing where the weights are specified when creating or editing each of the above question types.
