There are different equations that can be used to calculate confidence intervals depending on factors such as whether the standard deviation is known or smaller samples (n<30) are involved, among others. The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.". To do this, you will need to set up goals in Google Analytics.
