2x2 within subjects design (no repetition - counterbalanced)
I have a fully crossed 2x2 within subjects design in which participants will receive 4 stimuli that are accompanied by two different features (i.e. experimental factors).
Participants receive 4 statements and these statements are either a) approved or b) disapproved by a c) ingroup or d) outgroup.
Each participant should receive: 1 ingroup x approval image, 1 outgroup x disapproval image, 1 ingroup x approval image and 1x outgroup x disapproval image.
Group x feedback combinations should therefore randomly vary across the 4 images but each participant should receive all four possible combinations. This means, qualtrics needs to remember which combination has been shown and subsequently reduce the pool of options to present to participants.
Thanks in advance!
