In this video, we will take a deep dive into the fundamentals of metrics in A/B Testing. By the end of the video, you will have a solid understanding of the common types of metrics and tips for applying them in real-world A/B testing applications. Some ideas are inspired by the book Trustworthy Online Controlled Experiments: A Practical Guide to A/B Testing. I'm sure this video will be extremely helpful for both interview preparation and day-to-day work as a DS.
