After performing 1 simulation as the first step in his significance test, Finn does 99 more. For each simulation, he randomly reorganizes the subjects into two groups, A and B, of size 10. In the simulations, group A always plays the role of the treatment group and group B the role of the control group. After each simulation, he subtracts the average for group B from the average for group A.
