  • Help with randomizing trials

    I'm am trying to set up an experiment with trials from 2 different groups. I have 80 total different stimuli pictures. I want 40 to go to one group and 40 to go to the other group. Then, within that, i want to further break down the stimuli so that there are 4 more groups. Then within that, i want each group to be broken down to lookin 1 way or another. Is there an easy way to counter balance what goes where?

      Hisham,

      I will call soon. I still have a lot of trials to enter. I'm in the central time zone, you?

          When time permits, would someone mind posting some tips for counterbalancing items.
          As a newbie, it would be useful to see what methods people use.
