Recall that we said we needed to find all such rearrangements. We are going to find only three per group. Then we will pool all mean differences and count how many times we obtained means as extreme (farther from zero) as that of our original mean reaction distance. Run a re-randomization on your original differences two more times. Calculate and record the mean difference for each re-randomization.
