Illustrations are given of how a binomial sample-size table of limited scope can be used to address a wider range of problems. Necessary sample sizes for binomial differences not specifically covered ...

When particles in a sample are the same size, one particle can be measured to report the result. If the sample has a narrow distribution, such as 10-25 µm, then measurement of just a few particles can ...

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 ...
