For my thesis I have to do an online experiment with 4 conditions. I cannot figure out how to randomize different blocks with the same image..
What I want to accomplish: the same image (randomized of 4) in different blocks.
In addition, of the 4 conditions, 2 are dependent on nationality (Dutch and French). Is it possible to show a different condition depending on the answer respondents give on their nationality?
I hope this is clear.. I would really appreciate your help.
