The second day of the Workshop on Multilevel Models of the #asp is starting!
Yesterday, we learned about linear models and the importance of centering. Today, we will explore fixed and random effects, along with ICC, BIC, and AIC.
Excited for the day and grateful for participants' engagement!

The last effect size is inflated even though the mean difference between intervention and control isn't that large. But did you notice the very small SD?
This points to the confusion of SE and SD and is a serious issue for the overall results of the meta-analysis. 😬
