I would like to create a survey where there are 6 slightly different versions of it and they are randomly delivered to participants. Is this possible?
Have you heard of the percent branch action? Here is some info that I found on how it works: http://help.surveygizmo.com/help/article/link/branching-a-b-split-testing
Essentially it sounds like you could create 6 branches to have respondents randomly get assigned a path to the survey to take. You would just have to set up those paths for the different versions of your surveys.
Do you think something like this will do what you are looking for?
