In the Two-Sample Test for Proportions task, you can determine whether two probabilities are the same. The data analyzed in this example are taken from a study measuring the accuracy of two computer ...

This applet allows users to specify a hypothesized population proportion, sample proportion and sample size as well as an alternative hypothesis and significance level. After changing the values, the ...

In this article, we propose approximate sample size formulas for establishing equivalence or noninferiority of two treatments in match-pairs design. Using the ratio of two proportions as the ...

Simultaneous confidence interval procedures for multinomial proportions are used in many areas of science. In this article two new simultaneous confidence interval procedures are introduced. Numerical ...

Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...
