Hi all, I am analyzing a dataset from a classroom experiment and I found some issues.

The set up: IV1) within-subject factor; IV2) between-subject manipulation, randomized at the group level.

I think this can be complex to run since data is also clustered at the group level (students are teamed up). Ideally, I will need to run a mixed GLM with clustered error, right? If so, where/how can I run it?
