Hi, all!
I'm designing a survey that consists of presenting each participant with 4 stimuli (out of a total of 32) + 4 distractors (always the same), and, for each of them, 3 questions are asked. I will then randomly assign to each participant one of the 8 study conditions (8 groups of 4 pre-determined stimuli + 4 distractors, all 8 with their respective 3 questions). I thought an option would be to create 8 question groups, each with 8 question subgroups inside that would also be randomized, but there doesn’t seem to be possible to have question subgroups inside a question group, or is it?
Assuming that it’s not possible to have question subgroups, I thought I’d create 32 question groups + 4 distractors’ question groups, using rand() to assign 1 one the 8 conditions to each participant, and then somehow indicate in the question groups which condition they belong to.
I tested it with 4 question groups:
- created a hidden equation question with {if(random >= 1, random, rand(1, 2))}
- created question groups for each of 4 stimuli
- wrote (random ==1) in the relevance box for 2 question groups and (random ==2) in the relevance box for the other 2.
When I preview the survey, I get one question group from each of the conditions instead of getting the 2 questions groups of the same condition. Clearly I’m doing something wrong. Is this solution viable?
If yes, besides being able to show both questions belonging to same condition, I also don't know how to go about the distractors’ groups, which should appear in all of the conditions, randomly displayed together with the assigned 4 stimuli groups.
I’m so sorry if this is a silly question. I keep searching for answers in the forum but I really don’t know what to do.
I'm attaching my survey file. The version I'm using is 3.13.2+180709
I'd really appreciate any help.
