@teresap If you’re not familiar with JavaScript or embedded data, there’s a much simpler way to do this.

1. Create 2 blocks: Block A and Block B, each contain 6 image of it’s subset.
2. Using Advance Randomization to insert 3 question from the list of 6 for both blocks
3. Random the blocks order again in survey flow

This should give you 28,800 random permutation orders, which I think is enough.

Hope this helps

@Nam Nguyen thank you! I did not realize that randomizing with two blocks underneath would randomize all of the questions collectively. I appreciate your help!

Update: when I did this, it did allow me to randomize 3 questions from Block A and Block B into an overall of 6 questions, however it kept the sets together (so it would present 3 questions from Block A then 3 questions from Block B and vice versa). Is there a way for me to randomize the 6 questions, so that the sets of questions are not together?

@teresap There is but it will be much more complicated

@Nam Nguyen If you don’t mind explaining, I would love to try and create it despite the complications

@teresap Okay, so follow these step

1. Make your survey flow like this,
   Declare 6 imglink that will be use to store the result → “imglink1” to “imglink6”
   1 intro block for an intro question that will contain the shuffle JavaScript
   IMG block that will present 6 image in 6 question.

    

2. Add this JavaScript to you intro question, replace the imagelink of subset with your own.

   Qualtrics.SurveyEngine.addOnload(function() {
       // Define the image links for subset A and subset B
       var subsetA = a
           "link_to_image_A1",
           "link_to_image_A2",
           "link_to_image_A3",
           "link_to_image_A4",
           "link_to_image_A5",
           "link_to_image_A6"
       ];
   
       var subsetB = a
           "link_to_image_B1",
           "link_to_image_B2",
           "link_to_image_B3",
           "link_to_image_B4",
           "link_to_image_B5",
           "link_to_image_B6"
       ];
   
       // Function to shuffle an array
       function shuffle(array) {
           for (let i = array.length - 1; i > 0; i--) {
               const j = Math.floor(Math.random() * (i + 1));
               >array i], arrayrj]] =  array[j], arrayri]];
           }
           return array;
       }
   
       // Shuffle both subsets
       subsetA = shuffle(subsetA);
       subsetB = shuffle(subsetB);
   
       // Select 3 images from each subset
       var selectedA = subsetA.slice(0, 3);
       var selectedB = subsetB.slice(0, 3);
   
       // Combine the selected images
       var selectedImages = selectedA.concat(selectedB);
   
       // Shuffle the combined selected images
       selectedImages = shuffle(selectedImages);
   
       // Set the images to embedded data fields
       for (var i = 0; i < selectedImages.length; i++) {
           Qualtrics.SurveyEngine.setEmbeddedData('imglink' + (i + 1), selectedImagesei]);
       }
   });
   

    

3. Add the image link to your question with RichContentEditor → Source (Replace the “imglink1” from 1 to 6)

   <img style="width: 600px; height: 600px;" src="${e://Field/imglink1}">

    

   

    

@Nam Nguyen Thank you very much for your response. I found that the situation described in this post is very similar to mine, so I would like to ask some follow-up questions.

1. Declare 6 imglink that will be use to store the result → “imglink1” to “imglink6”   Could you please explain this a little bit more? Is there anything that I need to do to set this up and how should this be like?
2. Is it OK to directly use ${e://Field/imglink1} to ${e://Field/imglink6} as statements in the MCQs or Matrix questions? 

Thank you very much for your advice.
