st: RE: Robust equal variance test!Results?
Your P-values are much less than any standard level,
so conventionally you fail to reject (or even accept)
a null hypothesis of no difference. This is true on three
different criteria, so how you compute it is unimportant.
In any case, the results show simply that sd is about
0.7 in both cases.
