Question

Quizplus · Accepted Answer

Conducting a power analysis involves determining the sample size needed to detect a particular effect size with a desired level of statistical power, given a specific alpha level. Therefore, knowing the desired alpha level is crucial in conducting a power analysis. Gender distribution, standard error, and variance may be important factors in the study design, but they are not directly related to determining sample size through a power analysis.
