Web•The so called "exact method" of Clopper and Pearson (1). This is the only method Prism 6 (and earlier) used. No matter what data you enter, this method always ensures that the actual confidence level is greater than the level you requested (usually 95%). But often the actual confidence level is a lot higher. WebExact (Clopper-Pearson) confidence limits are available for the binomial proportion. For two-way tables, exact p -values are available for the following tests: Pearson chi-square test, likelihood-ratio chi-square test, Mantel-Haenszel chi-square test, Fisher’s exact test, Jonckheere-Terpstra test, and Cochran-Armitage test for trend.

The Clopper–Pearson interval is an early and very common method for calculating binomial confidence intervals.
