I have two different versions of the same survey (similar, but with different questions). I want to randomly present them to the user that clicks on the provided URL. The only constraint is that I need to assure that both versions are presented the same number of times (for instance, in 300 respondents, version 1 must be presented randomly to 150 users, the same in what concerns to version 2), so "pure" randomization is not an option.
But then I thought that maybe this could be possible inside SSI Web, maybe using one block for each survey version in conjunction with lists, or something. Is this possible? If yes, how?
Thank you very much,
