Hi
I have two sets of stimuli, say A and B. A has six items and B has five items. I want to pair each item from list A with an Itea from List B. So that:
A. In the experiment I have all 30 possible pairs
B. Each pair appears just once
C. The order of pair appearance is random
How can I achieve that?
Thanks much
Shlomo

Thanks much Shlomo Pair the item numbers using two linked <list>s, use those lists for item / pair selection. No different than https://www.millisecond.com/support/docs/current/html/howto/howtopairs.htm really.
