19. What is A/B testing, and how do you analyze the results? Comparing two versions (A & B) to see which performs better. Use t-tests or proportions test, check for statistical significance. 20. What is a Chi-square test, and when is it used? Tests independence between categorical variables. Used in contingency tables (e.g., is gender associated with purchase behavior?).
