S3E10 - Avoid AB Testing Statistics Mistakes with Max LI

A/B testing plays a critical role in decision-making - but so does AB Testing Statistics Mistakes. In data-driven companies, A/B tests not only prove positive impacts of product features (treatments) but also provide evidence to safely roll out neutral features that are not expected to move business metrics. When rolling out a neutral feature, we need to test if the treatment is non-inferior to control, and conventional A/B testing is not suitable in this case. In my talk, I present when conventional A/B testing would fail, what the non-inferiority test is, and how is non-inferiority test better when testing treatment is not worse than control.
