Dear all,
I would like to apply a advanced randomization for blocks that I can not seem to figure out.
I have 120 blocks including:
- 1 picture per block (12 different pictures in total)
- 1 text per block (9 different texts + 1 no text in total)
- all possible combinations of the above
Each participant is only going to see 12 blocks (i.e. the 12 different pictures). I want to make sure they do not see duplicates (e.g. the same picture or same text) and preferable and a random order. Does anybody have any idea how I can make this work?
Any help is appreciated!
Maurice
