Explorations in Statistics: Confidence Intervals
Curran-Everett, Douglas
Advances in Physiology Education, v33 n2 p87-90 Jun 2009
Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This third installment of "Explorations in Statistics" investigates confidence intervals. A confidence interval is a range that we expect, with some level of confidence, to include the true value of a population parameter such as the mean. A confidence interval provides the same statistical information as the P value from a hypothesis test, but it circumvents the drawbacks of that hypothesis test. Even more important, a confidence interval focuses our attention on the scientific importance of some experimental result. (Contains 5 footnotes, 1 table, and 3 figures.)
