The power of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number.
Statistical power. The power of a test sometimes, less formally, refers to the probability of rejecting the null when it is not correct, though this is not the formal definition stated above. The power is in general a function of the possible distributions, often determined by a parameter, under the alternative hypothesis. A common scenario is the comparison of the means of two data sets. The power is then the probability of getting that data, X, given the means are different. power = Pr ( X â£ Î¼ â  Î¼ 0 ) .
