LimeSurvey version: 5.2.12
==================
(Write here your question/remark)

Hi everyone,

I was trying to design a survey where one out of four groups of questions are randomised to display. Plus the questions inside one randomised group should also be randomised.

Now, I already implemented the one out of four group function through the randomisation group name + condition: equation + LT 1.

I have no idea of how to implement randomised questions inside the groups.

Please check my lss file in the attachments.

Please let me know if you have any ideas.

Thank you in advance!

Hi, there is always this confusing about the word "randomization".
It is user for 
  1. I want to show all groups but in randomized order
    Buzzword "Randomization group name"
  2. I want to show one out of x groups randomly selected.
    Buzzword "random number"
So to select one of the four groups you should create a random number (rn)
{if(is_empty(rn),rand(1,4),rn)}

and set the condition of 
Task1 : rn==1
Task2 : rn==2
...

And I assume the questions inside the groups you want to show in randomized order.
Here you set the "randomization group name" of the questions involved to the same name.


If I misunderstood, please explain again.

Where can I place this random number? In the group or in the first question? Can you explain in more detail?
