Sample‐size calculations use a variation of the type II error probability known as the power of the test. The power of a hypothesis test is the probability you’ll correctly reject the null hypothesis, in other words, the probability you’ll reject H0 when it isn’t true. It’s one minus the type II error probability, or 1−β. Sample size has a big impact on the power of a test, and if you gather enough samples, you can amass as much power as you like. Delving into the world of statistical power is a little like delving into the world of political power: messy.
