This is a comprehensive walkthrough of an A/B testing example. I will go through the details of designing A/B testing experiments, running experiments and interpreting results. The idea is inspired by the book Trustworthy online controlled experiments, a practical guide to A/B testing. I’m sure it will be extremely helpful for data science interview preparation.
