Hi. I am creating a choice experiment with four blocks, each containing six choice cards. I would like to know how to randomize the blocks, but not the choice cards. Each participant needs to receive a different block, each containing six choice cards. I understand that this can be done through random selection, but within each block, I need each choice card to be presented separately. This is the part I’m unsure about. TivAI Support mentioned using the Pro Editor, but I don’t fully understand how it works.
