Split random order was created by Andrea01
Is it possible to split random order for arrays, multiple choice and radio list questions?

For example question code Q1with subquestions

sq001 subquestion1
sq002 subquestion2
sq003 subquestion3

sq004 subquestion4
sq005 subquestion5
sq006 subquestion6

Subquestion1 to 3 should be in random order between themselves and additionally subquestion4 to 6 should be in their own random order.

Thanks in advance and best regards
Andrea

Hi, Andrea,

shortest and easiest way:

split it into two questions.

Thank you Joffm, I habe been thinking about this solution, but I thought there might be a more elegant way.

Also, I just discovered, that I put my request in the wrong forum. Can you please move it to forum "Can I do this with LimeSurvey" or should I post again.

Thanks,
Andrea

Hi, Andrea,
I know it's not very elegent.

But at the moment we only have workarounds for half of it: randomized first three, fixed second three.

Don't worry about the section, as long as you post in the correct language.
To be honest: Unfortunately nearly nobody seems to care about the intended content of the first three sections.


Best regards
Joffm

You could do it with JavaScript but the script details would depend on the LimeSurvey version used.

Place this in template.js:

Code:
function shuffleArray(array) {
  for (var i = array.length - 1; i > 0; i--) {
    var j = Math.floor(Math.random() * (i + 1));
    var temp = array[i];
    array[i] = array[j];
    array[j] = temp;
  }
  return array;
}

Place something like this in the source of a multiple-choice question (adjust the sub-question codes as required):

Code:
<script type="text/javascript" charset="utf-8">
 
  $(document).ready(function() {  
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
 
    // First group of sub-question codes
    var sqCodes1 = ['SQ001', 'SQ002', 'SQ003'];
    // Second group of sub-question codes
    var sqCodes2 = ['SQ004', 'SQ005', 'SQ006'];
 
    // Shuffle the subquestions
    shuffleArray(sqCodes1);
    shuffleArray(sqCodes2);
 
    // Insert the rows in the shuffled order
    $(sqCodes1).each(function(i, val){
      $('.subquestions-list', thisQuestion).append($('.question-item[id$="X'+qID+val+'"]', thisQuestion));
    });
    $(sqCodes2).each(function(i, val){
      $('.subquestions-list', thisQuestion).append($('.question-item[id$="X'+qID+val+'"]', thisQuestion));
    });
  });
</script>

Place something like this in the source of an array question (adjust the sub-question codes as required):

Code:
<script type="text/javascript" charset="utf-8">
 
  $(document).ready(function() {  
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
 
    // First group of sub-question codes
    var sqCodes1 = ['SQ001', 'SQ002', 'SQ003'];
    // Second group of sub-question codes
    var sqCodes2 = ['SQ004', 'SQ005', 'SQ006'];
 
    // Shuffle the subquestions
    shuffleArray(sqCodes1);
    shuffleArray(sqCodes2);
 
    // Insert the rows in the shuffled order
    $(sqCodes1).each(function(i, val){
      $('table.subquestions-list', thisQuestion).append($('.answers-list[id$="X'+qID+val+'"]', thisQuestion));
    });
    $(sqCodes2).each(function(i, val){
      $('table.subquestions-list', thisQuestion).append($('.answers-list[id$="X'+qID+val+'"]', thisQuestion));
    });
  });
</script>

Place something like this in the source of a list-radio question (adjust the answer codes as required):

Code:
<script type="text/javascript" charset="utf-8">
 
  $(document).ready(function() {  
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
 
    // First group of answer codes
    var answerCodes1 = ['A1', 'A2', 'A3'];
    // Second group of answer codes
    var answerCodes2 = ['A4', 'A5', 'A6'];
 
    // Shuffle the subquestions
    shuffleArray(answerCodes1);
    shuffleArray(answerCodes2);
 
    // Insert the rows in the shuffled order
    $(answerCodes1).each(function(i, val){
      $('.answers-list', thisQuestion).append($('.answer-item[id$="X'+qID+val+'"]', thisQuestion));
    });
    $(answerCodes2).each(function(i, val){
      $('.answers-list', thisQuestion).append($('.answer-item[id$="X'+qID+val+'"]', thisQuestion));
    });
  });
</script>

I modified the code provided by Tony and had sucess, it works in version 3.22.
Please find the code below for 3 groups, subquestions order by random in each group.

BUT: Is there a possibility for random order the groups too?
Would be perfect if I could random order groups and subquestions within the group!

Could anyone help?
thx, Andrea

<script type="text/javascript" charset="utf-8">

function shuffleArray(array) {
for (var i = array.length - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i + 1));
var temp = array;
array = array[j];
array[j] = temp;
}
return array;
}

$(document).on('ready pjax:scriptcomplete',function(){

// Identify this question
var qID = {QID};
var thisQuestion = $('#question'+qID);

// First group of sub-question codes
var sqCodes1 = ;
// Second group of sub-question codes
var sqCodes2 = ;
var sqCodes3 = ;



// Shuffle the subquestions
shuffleArray(sqCodes1);
shuffleArray(sqCodes2);
shuffleArray(sqCodes3);

// Insert the rows in the shuffled order
$(sqCodes1).each(function(i, val){
$('.answers-list[id$=X'+qID+val+']', thisQuestion).appendTo($('table.subquestion-list', thisQuestion));
});
$(sqCodes2).each(function(i, val){
$('.answers-list[id$=X'+qID+val+']', thisQuestion).appendTo($('table.subquestion-list', thisQuestion));
});
$(sqCodes3).each(function(i, val){
$('.answers-list[id$=X'+qID+val+']', thisQuestion).appendTo($('table.subquestion-list', thisQuestion));
});
});
</script>

This will also randomize the order of the sub-question groups:

Code:
<script type="text/javascript" charset="utf-8">
 
  function shuffleArray(array) {
    for (var i = array.length - 1; i > 0; i--) {
      var j = Math.floor(Math.random() * (i + 1));
      var temp = array[i];
      array[i] = array[j];
      array[j] = temp;
    }
    return array;
  }
 
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
 
    var sqGroupIndexes = [1, 2, 3];
    // The groups of sub-codes
    var sqCodes = {
      1: ['1', '2', '3'],
      2: ['4','5', '6'],
      3: ['7','8']
    }
 
    // Shuffle the arrays
    shuffleArray(sqGroupIndexes)[1];
    shuffleArray(sqCodes[1]);
    shuffleArray(sqCodes[2]);
    shuffleArray(sqCodes[3]);
 
    // Loop though the randomized indexes
    $.each(sqGroupIndexes, function(index, val) {
      // Insert the rows in the shuffled order
      $.each(sqCodes[val], function(index, val){
        $('.answers-list[id$=X'+qID+val+']', thisQuestion).appendTo($('table.subquestion-list', thisQuestion));
      });
 
    });
  });
</script>
