Algorithm for post hoc t-tests

1) Lowest 2 force levels were selected for comparison.

2) Coefficients of variation of the selected force levels were compared by testing for a significant difference between their means.

3) If the comparison from step 2 involved the highest force level, the algorithm stopped. Otherwise, the next highest force level was selected for a new comparison.

4) If the comparison from step 2 yielded a significant difference, the higher of the previously compared force levels was selected for comparison. Otherwise the lower of the compared force levels was selected.

5) Algorithm was repeated, starting at step 2.
