Accuracy in a multiple choice questionnaire

  Hi Vassilis,

  
  

  Can you try to put the code in the run phase of the inline_script? At prepare time, a choice hasn't been made yet.

  Thanks Eduard for your immediate response!

  Unfortunately, nothing has changed.

  However, I feel that the problem is elsewhere. I think that the correct_response variable is referred to a sting of letters, while the response variable of the multiple choice item is not an entity of letters, but rather clicking a box (i suppose). Thus, the problem may be that that correct_response and my_response are different entities. Then, I have to somehow match these two variables to another level, something I cannot imagine at the moment. I don't know if this has any meaning at all!

  Update:

  With your proposed change, the variable "correct" takes the correct values (0 or 1). However, the acc feedback always displays 0%.

  Okay, in that case, a first step is to print out the actual values. So, in your inline_script add the lines:

  print(var.response,var.correct_response)
  print(type(var.response),type(var.correct_response))
  
  

  Also, I just see a problem in your code. Can you replace this line

  if self.get('correct') == '1':
      self.experiment.total_correct += '1'
    
  

  with this line?

  if self.get('correct') == 1: # note, no quotation marks
      self.experiment.total_correct +=1
  

  Does the problem still persist?

  Btw. Please, if you present code, copy the text inside your comment. Screenshots of code are annoying to work with (can't copy & paste)
