Use this feature to determine the power of a two-sample proportion test given the sample size or the sample size required to obtain a specified power for two-sample proportion test .
Generally speaking, Power and Sample Size tools can be used in two ways: sample-size estimation and power computation. The former can be used to determine the size of the sample to ensure a certain power when you are designing an experiment. The latter can be used to estimate the accuracy of the result after you have conducted an experiment on a specific number of samples.
To perform a Power and Sample Size for two-sample proportion test :
