Why Aren't They Called Probability Intervals?
Devlin, Thomas F.
Mathematics Teacher, v101 n9 p647-651 May 2008
This article offers suggestions for teaching confidence intervals, a fundamental statistical tool often misinterpreted by beginning students. A historical perspective presenting the interpretation given by their inventor is supported with examples and the use of technology. A method for determining confidence intervals for the seldom-discussed population proportion when the Normal distribution is not a good approximation to the Binomial is also provided. (Contains 3 figures, 1 table and bibliography.)
