Hello,

I created two versions (A and B ) of a questionnaire and I would like that my respondents answer to one of these versions at random. Is it possible to send to the respondents only one URL address and Limesurvey will choose itself which one of these questionnaire will be answered?

Thank you very much for your answer.

Hi,
I see two ways of doing that
- Make one survey with several groups of question, that are enable or disabled, depending on a (hidden?) selection question.
- Make two surveys, and a selection webpage where the user is automatically directed to one of both surveys.
Good luck!

If you choose one survey, and questions and questions groups that depend on this answer, this function of expression manager will be useful: rand(1,2)

Indeed, and use this function as the default value of the question. Then it is evaluated only once.

A similar approach (based on questions, not surveys) is described at this blog post "How to randomly show 1 of X questions at a Limesurvey survey": www.limesurvey-consulting.com/how-to-ran...a-limesurvey-survey/ .
