Question

Quizplus · Accepted Answer

Statistical power can be improved by manipulating the alpha level, decreasing participant heterogeneity, and using a reliable measure for the dependent variable. Manipulating the alpha level can increase the likelihood of finding a significant effect, while reducing participant heterogeneity can increase the effect size and make it easier to detect. Using a reliable measure for the dependent variable can reduce measurement error and increase the accuracy of the results. All of these methods can contribute to increasing statistical power.
