I'm a bit a new hypothesis testing, so I hope that this question makes sense. Say that I proposed a new treatment (like a new drug or something) and I wanted to test whether this drug was effective or not.
I understand that Power Analysis can be used to help us determine the sample size that is necessary to detect a significant effect. However, this analysis will not account for novelty effects of said treatment.
One thing that I never understood, where are novelty effects accounted for in power analysis? Hopefully, I can advice from an expert!
Thank you!
