Randomised control trials have been a key part of medical science since the 18th century. More recently they have gained rapid traction in the e-commerce world where the term ‘A/B testing’ has become synonymous with businesses that are innovative and data-driven.
A/B testing has become the ‘status quo’ for retail website development - enabling product managers and marketing professionals to positively affect the customer journey; the sales funnel in particular. Combining event stream data with sound questions and good experiment design, these controlled trials become powerful tools for insight into user behaviour.
This talk will present a comprehensive overview of A/B testing discussing both the advantages and the caveats. A series of case studies and toy examples will detail the myriad of analyses possible from rich web events data. Topics covered will include inference with hypothesis testing, regression, bootstrapping, Bayesian models and parametric simulations.
