Reply To: Interferential Statistics Study Design – Power

[Chrissy Durrough Lugge]

Hi Jacqueline,

Thanks for pointing this out! You are correct – alpha and beta are inversely related. This is a typo; the question should read “increase the p-value”. Realistically, researcher would not want to use this method for increasing power. The question will be updated today to reflect this!

The question isn’t implying that the researcher would manipulate effect size – only that a larger effect size would result in increased power.

Thanks again!

Chrissy
