After gathering data, their XP’s analytic platform validates the data and detects two major issues for experimenters to watch for and to keep a healthy skepticism in their A/B experiments:

  • Sample size imbalance, meaning that the sample size ratio in the control and treatment groups is significantly different from what was expected. In these scenarios, experimenters must double check their randomization mechanisms.
  • Flickers, which refers to users that have switched between control and treatment groups. For example, a rider purchases a new Android cell phone to replace an old iPhone, while the treatment of the experiment was only configured for iOS. The rider would switch from the treatment group to the control group. Existence of such users might contaminate the experiment results, so we would exclude these users (flickers) in our analyses.
