I have a dataset of 300+ students with teacher-reported data. There are 17 total teachers that reported data on the students.
I would like to run a model that tests mediation where the mediator is a teacher-reported variable (the independent and dependent variables are observed and child-report, respectively).
I know how to run this type of model in SPSS and MPlus, but I'm not sure how to structure the data to account for the nestedness of students within teachers. Is there a line of syntax that indicates the clustered nature of the data?
