RegisterRepeats [Study Assessment]
Hi ElMaestro,
Yup I agreed. Just finished a study with n=60 and post-hoc power was 75%. Guess what, study passed 90%CI, intraCV was 55%. T/R ratio was 99%.

❝ Post-hoc power is to me not meaningful. I have no idea how to apply knowledge of that value. And stop up and think: What can you say about the power of a trial in which your PE is close to 0.79 regardless of sample size etc.?
