We have two groups of students divided into control and experimental group, with a specific teaching method being the intervention.
There are about 35-40 students in each group.
We are grading one of their assignments using a rubric which has 4 dimensions (or 4 parts). So each student will get a score for each of those dimension AND a total score on their assignment. We want to test the difference between scores for experimental vs. control group to see if the intervention had any effect.
I am planning to use a MANOVA test using the grades for the four dimensions/parts of the rubric as dependent variables.

- Does this approach make sense?
- Can I also include the total score as one of my dependent variables (so have 5 dependent variables)? or that doesn't make sense?
