WebbRather than just read about these things, you will understand better if you learn enough to perform some basic computations -- (a) given a test statistic, and some assumptions to apply under H0, to be able work out how to obtain a rejection region that yields a desired significance level alpha*, and (b) to compute the power at any given effect size (given … WebbHigh statistical power occurs when a hypothesis test is likely to find an effect that exists in the population. A low power test is unlikely to detect that effect. For example, if statistical power is 80%, a hypothesis test has an 80% chance of detecting an effect that actually …
