FAQ

What is statistical significance?↓

Statistical significance shows how likely it is that A/B test result differences are not due to chance. A 95% confidence level is typically required.

What is a p-value?↓

A p-value is the probability that the observed result occurred by chance when there is no real difference. The lower the p-value, the more significant the result.

How many visitors do I need for an A/B test?↓
