Yes, effective size is directly proportional to power in statistical studies. Power, in this context, refers to the ability of a study to detect a significant result. An increase in the effect size, sample size, or significance level leads to increased statistical power, assuming other factors remain constant. Specifically, the number of participants (sample size) is directly proportional to the power of the study, meaning that larger sample sizes enhance the study's power to detect significant effects [1] [2] [10].
