if an observed difference is greater than the corresponding shortest significant range, then we conclude that the pair of means in question is significantly different.









































if an observed difference is smaller than the corresponding shortest significant range, all differences sharing the same upper mean are considered insignificant, in order to prevent contradictions (differences sharing the same upper mean are shorter by construction).









































for our case, the comparison will yield:
