"""Meaningful significance and statistical significance are quite different. One can get very great statistical significance what a large random sample while have no impact on meaningful significance. A random sample of 25,000 would be sufficient for belt size to have a statistical significant impact on how people vote with no meaningful significance."""

But belt size is a continuous variable. We are talking about an ABX test, in which the answers are binary; true/false. Aren't these different topics?

• It would not matter if you just said above and below 36". Voting Dem. or Rep. is also a dichotomous variable. - Norm 13:05:20 06/26/09 (6)
