Quizplus · Accepted Answer

The statistical power of a test depends on both the size of the sample drawn from the population (a) and the size of the effect (b). The larger the sample size and the larger the effect size, the greater the statistical power. The reliability of the test (c) is important for the accuracy and validity of the results, but it does not directly affect the statistical power of the test.
