2021-01-28 · Make the confidence lower! If you have a 99% confidence level, it means that almost all the intervals have to capture the true population mean/proportion (and the critical value is 2.576). However, if you use 95%, its critical value is 1.96, and because fewer of the intervals need to capture the true mean/proportion, the interval is less wide. If you have your standardized z-score, this calculator will help you convert that to a confidence level for either one-sided or two-sided A/B tests. Enter Z-Score: (-3.50 to 3.50) Two-Sided One-Sided This is an online Confidence Limits for Mean calculator to find out the lower and upper confidence limits for the given confidence intervals.
