WebAug 1, 2024 · In the figure below, it can be seen that in order to achieve a statistical power of 80% (Y-axis), where the effect size is an absolute change of size 3 (green line), n=8 animals will be required (reading down to the X-axis). If the effect size you are interested in detecting is an absolute change of less than 2 (blue line), it will not be ... WebThe power of a test is calculated as 1-beta and represents the probability that we reject the null hypothesis when it is false. We therefore wish to maximize the power of the test. The XLSTAT-Power module calculates the power (and beta) when other parameters are known.

WebStatistical power is the most commonly used metric for sample size determination. The power is the probability that the study will be able to detect a true effect of a drug or intervention of a specified size or greater. In statistical hypothesis terms, power is the probability of rejecting the null hypothesis when it is false.
