Randomize group between groups was created by plab
Hi there,
I want to do the survey like this:
I have 800 respondents, they will be randomly assigned to two groups. (G1 and G2)
And then after answer a few questions, they will be randomly assigned to the other two groups, each group will have 200 respondents.
How can I use LimeSurvey to do this? many thanks.

Without plugin and some PHP dev : there are no solution.
You can only have random solution.
For a random solution:
1. Create CHOOSE Équation question type
2. Put {alea(1,4)} for the equation
3. Put condition on G1 : CHOOSE <= 2
4. Put condition on G1-1 : CHOOSE == 1
With plugin using beforeSurveyPage : you can set value for CHOOSE (the don't set Equation for this question, just an hidden question).
