In Reply to: RE: I would quibble with what you say, but here I would really insist that you say statistical significance. posted by Norm on June 25, 2009 at 20:32:43
"Meaningful significance and statistical significance are quite different."
An essential distinction.
There are two steps involved in going from statistical significance to meaningful significance. The first step bridges the gap from correlation to causation. The second step bridges the gap between an effect and a meaningful effect. Both steps are frequently contentious, as can be seen in numerous threads in this forum. The first step can be accomplished with a causal model, the second step requires a set of values.
Those people who view the world in terms of crude (e.g. black or white) facts should stay well away from anything to do with statistics.

Causation and explanation are the next steps in providing an understanding. I am mainly concerned with people dropping "statistical" and assuming that what they have found is meaningfully significant. You find this quite prevalently in research literature in the social sciences.
pounding of ones' chest ... I suggest you do a little searching and add if you locate as the addition would be a nice finishing touch to your post.
Everything matters, don't forget to tweak your placebos!
