I am a novice to Inquisit and I am trying to code an experiment in which participants are first randomly assigned to one of two possible groups, and then further randomly assigned to one of 3 groups within the parent group. I am not sure how to accomplish that. Currently, the code I have written is just for the child group, seen below. I am not sure how to layer this into a parent group, and I'm not even sure if I am approaching this correctly in the first place. I am planning to run this through Inquisit Web using a participant pool from Prolific, if that makes a difference! Thank you in advance for any help.


<variables>
/ group = (1 of 3) (firstblock=data_50, secondblock=data_500, thirdblock=data_10000)
/ group = (2 of 3) (firstblock=data_500, secondblock=data_10000, thirdblock=data_50)
/ group = (3 of 3) (firstblock=data_10000, secondblock=data_50, thirdblock=data_500)
