Role of Randomization in A/B Tests
3/10
Why is randomization critical in A/B testing?
A
It ensures control and treatment groups are comparable, allowing differences in outcomes to be attributed to the treatment
B
It ensures the metric distribution is normal in both groups, validating the use of parametric tests
C
It guarantees the sample size is sufficient to detect the minimum detectable effect at the chosen power level for the experiment design
D
It prevents users from switching between groups during the experiment, ensuring clean group membership
