How do you handle the multiple comparisons problem in A/B testing?
Tests your grasp of statistical risk in experimentation. Explain how multiple tests inflate false positives, then describe mitigations like Bonferroni correction or limiting concurrent tests. A red flag is suggesting total test isolation, which is impractical.
This tests your understanding of statistical risk in a high-velocity experimentation environment. A strong answer defines the problem (more tests = higher false positive chance), explains the business cost (wasted effort), and details mitigations. Discuss statistical methods like Bonferroni or Benjamini-Hochberg and system approaches like limiting concurrent tests. The key red flag is proposing impractical solutions like complete test isolation, ignoring that users see combined effects.
