WebWhen sample.type="one.sample", the computed half-width is based on a confidence interval for a single mean. When sample.type="two.sample", the computed half-width is based on a confidence interval for the difference between two means. The default value is sample.type="one.sample" unless the argument n2 is supplied. WebIf you are interested in a CI from a single group, then to calculate the confidence interval you need to know the sample size, sample standard deviation and the sample arithmetic average. If entering data for a CI for difference in proportions, provide the calculator the sample sizes of the two groups as well as the number or rate of events ...
