Accuracy in a multiple choice questionnaire
Hey there!
I’m currently trying to build a multiple choice questionnaire, which will finally display the acc% of the correct responses.
My crucial problem is, that I cannot link the response variable of the multiple choice item (let's say my_response) to the correct_response variable (a variable that i defined through the loop, see the first image)
Then, I wrote the following inline script but the matching of the correct_response and my_response variables was not possible (and subsequently acc% was always 0). Any suggestions?
Kind regards,
Vassilis.

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:
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 +=1Does 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)
