I walk you through how to perform power analysis using the "pwr" package in R and discuss ways to determine the effect size that you would expect to observe.
Here are some links to a few things I mentioned:
1. "pwr" package: cran.r-project.org/web/packag...
2. "ANOVApower" package: github.com/Lakens/ANOVApower
3. TOSTER package: cran.r-project.org/web/packag...
4. Why you shouldn't use pilot data for calculating power: psyarxiv.com/b7z4q
5. My Effect size distribution paper: www.ncbi.nlm.nih.gov/pubmed/2... and preprint osf.io/5y55v/
6. Registered Reports: cos.io/rr/
7. Equivalence testing primer: journals.sagepub.com/doi/pdf/...
