Hi, all, I'm clinical psychology graduate student, and I'm analyzing my master's data at present. I have a design in which
small groups of participants (random nested factor; roughly 4 to 16 participants per group), were randomly assigned to one of two experimental conditions (fixed b/w subjects factor). Each participant completed measures at four time points (within-subjects factor). Basically, I need to run a nested-design, mixed-model ANOVA.
I've attempted to run this design by using Analyze->Repeated Measures, and then entering syntax for a nested variable, but SPSS says this design isn't allowable. If anybody has suggestions, they would be much appreciated!
