Randomize two sets of answer choices was created by wendyt

Dear fellows,

I'm a new LimeSurvey user and would like to see if we can set the radio question with 2 sets of answers. I checked there are ways to completely randomize all choices or partially with fixed order. But I cannot find a way to manage in particular the below:

Set 1:
Strongly agree
Agree
Neutral
Disagree
Strongly disagree
Don't know

Set 2:
Strongly disagree
Disagree
Neutral
Agree
Strongly agree
Don't know

Thank you very much!

Hi, wendyt,
maybe there is a way to do this with Javascript.
But here are two ways to do it just out of the box.

1. Create two questions (Q1A and Q1B) with answer options:
Q1A:
1 =Strongly agree
2 =Agree
3 =Neutral
4=Disagree
5=Strongly disagree
9=Don't know

Q1B:
5=Strongly disagree
4=Disagree
3=Neutral
2=Agree
1=Strongly agree
9=Don't know

Create a random number and display the questions according to that number. For analysis you get always the same codes.

2. Tayloring:
Create a random number. (rn)
create your answer options like:
1 = {if(rn==1,"Strongly agree","Strongly disagree")}
2 = {if(rn==1,"Agree","Disagree")}
...
9=Don't know

In this case you have only one question, but you have to recode the codes for analysis.
E.g. "if (rn=2) and (code<>9) then code=6-code"

You can do this either in your analysis software, EXCEL, OpenOffice, SPSS, or whatever.
But you can do it in LS by Expression Manager, too.

Here is a JavaScript solution to randomly invert all except the last answer within a single question.

Set up your survey to use JavaScript and place the following script in the source of the question:

Code:

<script type="text/javascript" charset="utf-8">
  $(document).ready(function(){  
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
 
    // Generate random number between 1 &amp; 2
    var rand = Math.floor(Math.random() * 2) + 1
 
    // If the random number = 2...
    if(rand == 2) {
      // Reverse the answer order (excepting the last answer)
      var lastAnswer = $('.answer-item:last', thisQuestion);
      var tr = $('.answer-item', thisQuestion).not(lastAnswer).detach().toArray();
      tr.reverse();
      $.each(tr, function(i, el) {
        $('.answers-list', thisQuestion).append(el);
      });
      $('.answers-list', thisQuestion).append(lastAnswer);
    }
  });  
</script>
