WebbThe coefficient of variation (CV) is a measure of precision from repeated measures. Within the lab, it is mainly used to determine how reliable assays are by determining the ratio of the standard deviation to the mean. The CV is the expressed as a percentage to easily determine the variation of the assay. WebbUsing the same statistical analysis procedure, the ratio of geometric means (untransformed), 90% confidence intervals, cvs, cve, MSS, and MSE were computed to confirm whether so calculated sample size would warrant that the ratio of geometric means falls within 80% - 125%. The result from a simulation pivotal study is shown in …
