If I understand Moodle correctly, I am allowed to assign a grade to each answer in a multiple-choice question, but this assignment applies only if that answer is selected (checked) by a student. What I would like is that each answer participates evenly on the final grade if it is correct, where correct may be both checked or unchecked.
A simple example: a question has 3 answers, the first one is correct if it is checked (C), the other two are correct if they are unchecked (U). In that case, if a student checks all the answers (CCC), only the first one is correct and the grade should be 33,3%. If the student leaves all the answers unchecked (UUU), the first one is incorrect and the others are correct and the grade should be 66,7%.
I don't know how to apply such grading. The one option would be to assign grades to unchecked answers. Is it possible? The other option I see would be to assign 100% to the first (should-be-checked) answer and -100% to the other (should-be-unchecked) answers. But then, I would additionally need to add 200% to the result and finally divide it by 3. Is this possible?
Re: Positive grade for unchecked correct answers in a multiple-choice question
Hi Daniel,
You may have your reasons but I do find your reasoning weird. Could you please provide a real-world example? From your example I suppose you want to use the multiple-choice, multiple-answer question.
"If the student leaves all the answers unchecked (UUU), the first one is incorrect and the others are correct and the grade should be 66,7%." That is not possible, if no answer is checked, the student will get the message "Please select at least one answer."
Re: Positive grade for unchecked correct answers in a multiple-choice question
I am new to Moodle, so maybe I do not express my ideas with the right words, sorry for that. I will try again and simpler. I have a question and then multiple statements (choices/answers). Each statement may be either true or false. Then, I want a student to choose either true or false for each statement. If this choice is correct, then it should add (100% / N) to the final grade, where N is the number of statements. If it is not correct, is shouldn't add anything to the final grade.
I might have used a wrong type of question. I now tried the "OU multiple response" but this does not seem to work either.

Hi Daniel,
We've all been "new to Moodle" once, don't worry.
Unfortunately you did not answer my suggestion of providing a real-world example of your question. There is a question type which is not currently available from the Moodle plugins directory, which might fit the bill. It's available from GitHub at Multiple True False (ETH). You don't say if you are an admin of your moodle site or a "simple" teacher. You would need Admin role to install this question type. Does it do what you want? See screenshot below. If not, please provide a real-world example (again)!

Re: Positive grade for unchecked correct answers in a multiple-choice question
thanks a lot again. Just a final note you might be interested in. I was advised that there is another option without a need of a third-party plugin — this is the Cloze question type. There, I can define as many answers as I like with true/false correct options, such as:
False correct answer {:MCV:TRUE~=FALSE}
True correct answer {:MCV:=TRUE~TRUE}
And, this is exactly what I wanted. The only downside is that the grades must be integer numbers. If I have 5 answers, then it implies minimal total grade 5 for that question (where I would like, for instance, 3). But this can be resolved at the quiz level. It's a bit bothersome since one can forget about it and make a mistake, but it works as a workaround.
