WebYou can decrease your risk of committing a type II error by ensuring your test has enough power. You can do this by ensuring your sample size is large enough to detect a practical difference when one truly exists. The probability of rejecting the null hypothesis when it is false is equal to 1–β. This value is the power of the test. WebType 2 (=β) is related with the power of the study, i.e. Power=1-β. It's the probability of finding the difference when it exists. The most common value given is β≤0.20 (Power of 80%)
