“proving” your hypothesis). Statistical power, or sensitivity, is the likelihood of a significance test detecting an effect when there actually is one. A true effect is a real, non-zero relationship between variables in a population. An effect is usually indicated by a real difference between groups or a correlation between variables. Statistical power is the probability of finding a difference that does exist, as opposed to the likelihood of declaring a difference that does not exist.

The power of the test is the probability of rejecting the null hypothesis, assuming that the true population proportion is equal to the critical  G*Power and Statistical Analyses.

Thus, power is inversely related to statistical significance while being positively related to the sample size and the minimum effect of interest. 2010-05-31 · The power of any test of statistical significance will be affected by four main parameters: the effect size the sample size (N) the alpha significance criterion (α) statistical power, or the chosen or implied beta (β) All four parameters are mathematically related.

In addition, the statistical power to detect at least one effect is 100% in both the WD and SL scenario, irrespective of the sample size. Panel (b) demonstrates that the mean absolute estimated effect size (for statistically significant voxels G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses.

2010-05-31 · In plain English, statistical power is the likelihood that a study will detect an effect when there is an effect there to be detected. If statistical power is high, the probability of making a Type II error, or concluding there is no effect when, in fact, there is one, goes down. Statistical power is affected chiefly by the size of the effect and The statistical power of a study (sometimes called sensitivity) is how likely the study is to distinguish an actual effect from one of chance.
