Statistical Significance

Statistical significance is a conclusion reached in an A/B test when the data shows that the observed result is very unlikely to have occurred due to random chance. It is typically determined by calculating a p-value. If the p-value is below a predefined threshold (usually 0.05), the result is considered statistically significant, giving you confidence that the change you made (e.g., improving page speed) was the actual cause of the measured improvement (e.g., a higher conversion rate).
