LimeSurvey Cloud Version 6.8.2
Hi,
I would like to create a questionnaire consisting of 10 questions, with the first two questions being the same for all respondents. Starting from the third question, I would like to introduce randomization:

• Respondents would be randomly assigned to receive one of two versions of the questionnaire (50% Version 1, 50% Version 2).

However, I would like this randomization to be stratified based on the responses to the first two questions (e.g., gender, age, or socio-professional category) to ensure that the groups receiving Version 1 and Version 2 are balanced according to these characteristics.Could you please confirm if LimeSurvey allows such stratified randomization? If yes, could you provide detailed instructions on how to set it up?Thank you very much for your assistance.Best regards,

Hi,

Could you please confirm if LimeSurvey allows such stratified randomization? If yes, could you provide detailed instructions on how to set it up?

Before I try to find a solution, please provide the lss export of this part of your survey.
How many categories of gender, age, ...?
And please explain what exactly you mean by "balanced"?

What comes to my mind at first, is "statFunctions".

Let's see
