Assessment survey with certainty-based marking was created by yannickfe
Hello everybody,

I'm trying to create an assessment survey where the points you receive depend on your certainty that you have picked the right answer ( certainty-based marking ).

So after each thematic question there should be a second one where the participants indicate their certainty (1 = low, 2 = mid, 3 = high).The participants are suppossed to gain or lose points for their answers according to the marking scheme attached to this post. After each of these question pairs there should be a feedback how many points were gained/lost and the points should be added up throughout the survey.

Is it possible to make assessment values dependent on the combination of two answered questions (in this case the thematic question and the certainty question)? Or maybe someone has a different idea on how to implement this marking scheme in limesurvey.

Any advice or suggestions would be greatly appreciated.

Thank you!

You can use Expression Manager nested IF() statements to populate an equation question with the score for each question pair.

For example, with question codes "Q1" and "certainty1" and the correct answer code "A1", something like this (line-breaks added for clarity):

Code:
{if(Q1 == 'A1' AND certainty1 == '1', 1, 
  if(Q1 == 'A1' AND certainty1 == '2', 2, 
    if(Q1 == 'A1' AND certainty1 == '3', 3, 
      if(Q1 != 'A1' AND certainty1 == '1', 0, 
        if(Q1 != 'A1' AND certainty1 == '2', -2, 
          if(Q1 != 'A1' AND certainty1 == '3', -6))))))}
Cheers,
