A/B Test Sample Size Calculator | Vwo. Go to your optimize account ( main menu > accounts ). Your experiment is therefore designed to have 0.8 or 0.9 probability of detecting.
It also tells you how long the tests should run to finally achieve. Go to your optimize account ( main menu > accounts ). Use 50% if not sure. Play around with the calculator and get a better feel for how baseline conversion rate and desired lift affect sample size and test duration. Those 10 are the sample and the 50 are the population. What sample size do i need? Just put in the confidence level, population size, margin of error, and the perfect sample size is calculated for you. Percent of the time a difference will be detected, assuming one does not exist. A conversion rate of e.g. Unlike ab tasty, it doesn’t just tell you the results.
