Examples of Z-score Calculations - ThoughtCo The best way to calculate UX ROI is by A/B testing. \(\sigma\) is the standard deviation of the population, then. 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.".
