In Part 2: What is an A/B Test we talked about testing the Top 10 lists on Netflix, and how the primary decision metric for this test was a measure of member satisfaction with Netflix. To build intuition, let’s run through a thought exercise. But how do we know if we’ve made the right decision, given the results of the test?
