It was shown, by two different procedures (Bootstrap and IntraPermutations that the length difference between female and male spider was, in mean values, 2.21 mm.
__a) For alpha = 5% we have:
_______________________________________ ______________0______1.76____1.21________Intra _____________________1.747___1.210_______Boots
__b) For alpha = 1% we have:
____________________________________ ______________0____1.63____1.21________Intra ___________________1.600___1.210_______Boots
It was fine, I mean, that People  against  NHST get aware how wrong are: in fact it´s easy to conclude that at least one can warrant that the difference are AT LEAST 1.76mm (1.747) with 95% probability and 1.63 (1.60) with 99% . . . By the reasons yet indicated the IntraPermutation method because do not distorts data (contrarily to Bootstrap) is candidate to be the better (preferable) one. It is true that they show (almost) complete concordance.
