Question
In hypothesis testing, what is the purpose of conducting a power analysis? A. To determine the p-value B. To calculate the effect size C. To estimate the probability of a Type II Error D. To define the null hypothesis
Solution
The purpose of conducting a power analysis in hypothesis testing is C. To estimate the probability of a Type II Error. Power analysis helps in determining the sample size required to detect an effect of a given size with a given degree of confidence. Consequently, it allows us to estimate the probability of a Type II Error (failing to reject the null hypothesis when it is false).
