Understanding Type I Errors, Type II Errors, and P-values

WebbPower analysis is a method for finding statistical power: the probability of finding an effect, assuming that the effect is actually there. To put it another way, power is the probability of rejecting a null hypothesis when it’s false. Note that power is different from a Type II error, which happens when you fail to reject a false null ...
