##### Randomly combining two sets of stimuli
 Author Message shareli@univ.haifa.ac.il Group: Forum Members Posts: 15, Visits: 109 HiI 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 pairsB. Each pair appears just onceC. The order of pair appearance is randomHow can I achieve that? Thanks muchShlomo Dave posted Last Month ANSWER Group: Administrators Posts: 12K, Visits: 100K +x shareli@univ.haifa.ac.il - 5/22/2024HiI have two sets of stimuli, say A and B.
