I have a 2x4 factorial design and was wondering if it is possible to do show the respondents a specific pair of blocks and still randomize the order? I need two different blocks displayed to every of the three treatment groups. So, let’s say there is Method A, B and C (one respondent should only see one of them), and each has part 1 and 2 (one respondent should see both within the method displayed to him). I found how the randomly display either A, B or C. Right now I have 1 and 2 together in one block, however it is necessary that 1 isn’t always displayed first, so that this is also randomised within the three methods, but I can’t seem to make sub-blocks within one block. I hope I explained this so people can understand. Would be great if someone could help. Thank you!!!
