Frequentist Multilevel Model in JASP (with Group Mean Centering)

Hi everyone, this is a tutorial for conducting and interpreting frequentist multilevel models in JASP. I discuss and compare a varying intercepts only model and a varying intercepts and slopes model.
The analysis is based on our paper published in PARE: openpublishing.library.umass....
The data are from Bliese and Halverson (1996) and the paper referenced for interpreting AIC is by Burnham and Anderson (2004).
