Dear group, It seems to me that the one issue here is that when we measure something, then that measure should have some meaning that is relevant to the study hypotheses. And that meaning should be interpretable so that the width of the CI does have meaning...why would you want to estimate the mean if it is "meaningless"? Warren May
