Varsity A/B Testing

When you want to understand if doing something causes something else to happen, like if a change to a website causes and dip or rise in downstream conversions, the gold standard analysis method is to use randomized controlled trials. Once you’ve properly randomized the treatment and effect, the analysis methods are well-understood and there are great tools in R and python (and other languages) to find the effects. However, when you’re operating at scale, the logistics of running all those tests, and reaching correct conclusions reliably, becomes the main challenge—making sure the right metrics are being computed, you know when to stop an experiment, you minimize the chances of finding spurious results, and many other issues that are simple to track for one or two experiments but become real challenges for dozens or hundreds of experiments. Nonetheless, the reality is that there might be dozens or hundreds of experiments worth running. So in this episode, we’ll work through some of the most important issues for running experiments at scale, with strong support from a series of great blog posts from Airbnb about how they solve this very issue.
