Statistical significance indicates whether observed differences in your data are likely to be real or just due to random chance. A result is typically considered statistically significant when there's less than a 5% probability (p < 0.05) that the observed difference occurred by chance.
A confidence interval provides a range of values that likely contains the true value of a metric. A 95% confidence interval means that if you repeated the experiment 100 times, approximately 95 of those intervals would contain the true value.
