Hi everyone!

I have some trouble finding the right solution for a randomization issue:

The goal is to get 5 hidden questions containing a random number between 1 and 5 with the additional condition that among these 5 questions every number can only occur=12.0pt once.
While getting random numbers seems to be quite easy, I do not know how to implement my additional condition.

To get the random number this works just fine: {if(is_empty(RandomPosition1), rand(1, 5), RandomPosition1)} however I am in need for some advice regarding my additional condition.

Thanks in advance!
 

Hi,
this is nothing else than to have the number 1,2,3,4,5 in randomized order. (if I translate this "can only occur=12.0pt once" correctly)
This you can achieve easily with a small javascript snippet.
Create a question of type "multiple short text" with 5 subquestions and insert this snippet into the source code You will get 5 unique numbers between 1 and 5
 


But first make sure that you have the rights to insert javascript (I see "university" installation)
To check, insert this in the source code of a question
But you should explain a bit more what you want to achieve. Maybe we can advise a better solution.

Here - in the German part - is a solution without javascript, only some equations (See 2. Das "Ziehen ohne Zurücklegen" nachgestellt.)

Thanks a lot Joffm. Javascript is working with my installation.

One additional question to your Javascript solution: The script perfectly gives me randomized numbers but I want to use the numbers to specify further conditions. However my conditions do not work unless I press enter (or anything else) in one of the 5 subquestions of the Javascript. Is there any solution for that? My goal is to hide the Javascript question. I attached a .lss document for visualisation.

Thanks in advance!

Hi,
nearly everything is fine, except:
1. You want to display "question by question".
This is not advisable.
The script cannot be hidden by "Always hide this question", but by javascript.
Well, you can run the script and at the end trigger the "Next"- button. But it will cause an unpleasant flicker of the page.
Therefore we recommend to display "group by group" and put one question into each group.
This way you have more options:
Fake the display "question by question", in some cases display two or more questions on on page, do some manipulations using javascript.
 
2. The question with the javascript must not be on the same page. Put it into a different group at the beginning of the survey.
As you see this line

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

the script starts after the document is loaded (ready).
Meaning: Your question "question" is displayed before the script works.

3. To hide it
There are these to lines in the script//    After testing remove the slashes of the next row to hide this question
//    $('#question{QID}').hide();So, do it: remove the slashes to hide the question.

Here two sample survey with both options
"question by question"
 

"group by group"

By the way:
Your first requirement was

The goal is to get 5 hidden questions containing a random number between 1 and 5

This you got. Not more.
You did not say what you want to use it for.
If you tell us a bit more there may be a better solution to aim your goal.

Always remember: Help us to help you.

Furthermore you may use the example in the German part (without javascript, only equations)
So there are no restrictions about "question by question" vs. "group by group", etc.

Here a sample survey for your requirements

Thanks a lot Joffm! That was very helpful!
