I am designing a survey flow in Qualtrics. I have two blocks items (X and Y) that I would like to randomly place either before or after other other blocks of the survey (A,B,C) For example, I want exactly one of these two orders-- XYABCD or ABXYCD -- to be randomly assigned to the subjects.
I have randomly assigned questions in a block and randomly included (or omitted) a block, and randomized when a block is included...but I don't see the technique to randomize across one of two locations.
Online help directs me how to
- randomize whether and where a block appears (random block location),
- randomize question order in a block,
- randomize response options to a question, and
- randomize questions appearing in a block (e.g., treatment v control condition)
- make a block of questions appear a second time later in the survey
but not randomize a block to appear in only 1 of 2 places
Add a randomizer and under it set an embedded data field to 1 or 2, evenly displayed. Then add branches to the survey flow to display XY before ABC if 1 or after ABC if 2.
