Dear Millisecond community,
I have programmed an experiment comprising 6 different experimental conditions. I would like to have these conditions counterbalanced within my 2 experimental groups, so that each condition is repeated an equal number of times within each group. I plan to have 82 participants in total, so 41 per each group.
The code below assigns every 6th participant to a specific condition, the problem is that in the end, conditions are not equally distributed within the 2 groups. For example, condition 4 gets repeated 9 times in group 1 and only 5 times in group 2.
Do you have any idea how I could modify the code so that each 6th participant is assigned to a specific condition within each group, and each condition is repeated an approximately equal number of times in both groups?
I would really appreciate the help!
