Question: True or false: Statistical significance is an optional part of A/B testing.
- True
- False
Explanation
An A/B test depends on enough data to determine whether one variation performs better with confidence. Statistical significance helps prevent decisions based on random variation or personal preference. Without it, the result should be treated as inconclusive rather than actionable. Reliable optimization requires continuing the test, adjusting the variable, or gathering more data before making a change.
Why the other options are incorrect
True is incorrect because statistical significance is required for confident A/B testing decisions.
