3.1 Further reading
How to justify your sample size (Lakens, 2022).
My tutorial with Lisa DeBruine (DeBruine & Barr, 2021) which covers much of the same ground, but is mainly focused on understanding how LMEMs work
Other articles on power in LMEMs: (Brysbaert & Stevens, 2018), (Kumle et al., 2021), (Westfall et al., 2014)
Monte Carlo simulations comparing methods for getting \(p\)-values: (Luke, 2017)
Check out the online textbooks and resources that my group and University of Glasgow have been developing. There are great resources to learn more about data wrangling and visualization, among other things.
