## PowerTOST: Total sample size [Power / Sample Size]

Hi Sereng,

❝ […] I believe you are stating n=750 per group in this parallel group study (total n=1500) using the assumptions from the completed study? Correct?

Nope. Pasted from my previous post:

Sample size (total)  n     power 750   0.800246

The sample size functions of PowerTOST give always the total sample. If you are interested in the background, see this article.
