WebbStatistical power is the probability of having made a correct decision when the statistical tests reveal insignificance (P greater than .05) and the null hypothesis is true. The higher the power, the greater the chance that the decision is correct. Webb18 jan. 2024 · In statistics, power refers to the likelihood of a hypothesis test detecting a true effect if there is one. A statistically powerful test is more likely to reject a false negative (a Type II error). If you don’t ensure enough power in your study, you may not be able to detect a statistically significant result even when it has practical significance. rap robux https://neisource.com
