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.
