  • "p- value --> Assuming the null hypothesis is true, probability of observing the data as extreme as the observed data. Example - You're running an experiment on a new checkout flow. Control converts at 10.0%, treatment converts at 10.8%. You run a two-sample z-test and get p = 0.03. What this means: If there were truly no difference between control and treatment (null hypothesis), there's only a 3% chance you'd see a difference of 0.8pp or larger just from random sampling noise."
