Negative Scoring for questionmult
Added by VInay Wagh 11 months ago
- All blank -- 0 marks
- Only and exactly the correct ones are marked -- 1 mark
- All other cases (i.e. partially correct, partially incorrect) -- MINUS half marks.
I am unable to achieve the combination of the parameters in scoring. My (one of the) attempt(s):
\scoringDefaultM{b=1,m=-0.5,p=-0.5,e=-0.5,MAX=1}
Can someone help me with the options?
Thanks

If my question has A and D are correct options.
- If a candidate marks ONLY A and D -- he gets 1 mark
- If a candidate marks ONLY A -- he gets MINUS half mark
- If a candidate marks A and C -- he gets MINUS half mark
- If a candidate marks B and C -- he gets MINUS half mark
- If nothing is marked -- he gets ZERO

You can try something like that:
\scoring{b=0,m=-2,d=1,p=-0.5}
b=0
to score zero points when properly ticked or notm=-2
to score -2 points when an correct answer is not ticked or a wrong anser is ticked
Then the score will be 0 when all is OK or ≤-2 when something is wrong.
Then d=1
adds 1 to the total score, so that the score is now 1 when all is correct, or ≤-1 when something is wrong.
Then p=-0.5
sets a ceiling value to -0.5, leading to the required result.
Alternatively, you can use a formula:
\scoring{formula=(N==NBC+NM-NMC ? 1 : -0.5)}
Here, N
is the number of answers, NB
number of correct answers, NBC
number of correct ticked answers, NM
number of wrong answers, NMC
number of wrong and ticked answers.

Thanks @Alexix, for a quick response! The strategy given in your reply works flawlessly! Exactly the way I wanted it to work...
Regarding the "Test Scoring", it took me some time to understand `how to use', but it was smooth once it clicked! A frank feedback: the modus operandi is a bit less intuitive!
Thanks once again!
