Description
Would it be possible to automatically calculate penalties for wrong answers depending on the number of choices in a multiple-choice question?
This seems like a logical scheme.
For example,
minus 20% if there are 5 choices (0.20)
minus 25% if there are 4 choices (0.25)
minus 33.3% if there are 3 choices
minus 50% if there are 2 choices (Maybe even 100% in this case.)
Hi Charles, I think that the penalties that you suggest are no correct.
Penalties are applied because in a random answer, the moment (average value) was 0. For this you have to calculated with the formula:
penaltie = 1/(k+1) where k is the nomber of choices.
