MANCOVA and MANOVA Discussion > MANCOVA help
Dear Ali,
First of all, allow me to apologize for the extremely delayed nature of my response. Unfortunately, my forum notifications were being sent to an inactive email, so I didn't become aware of new posts for a long time. In regards to your question, I'm afraid it is a very large and complex question, and it's is probably beyond the scope of what can be answered on a discussion forum. If you have more specific questions about the process, it is more realistic to post those and have them answered, but it would be tough to guide you through the entire process.
If you are looking for more in-depth assistance, you might consider exploring my consulting service. Otherwise, feel free to post more specific questions with a more narrow scope. Best.

I wanted to test the effectiveness of a new teaching method. I asked 5 teachers to use this new method in their classes, and used 5 other classes as a control group. I also thought that this method might be more effective with, say, low-achieving students than others, so I divided the students in each class into high-, average, and low-achieving students.
To test this method, I used two criteria for all the above students: tests & questionnaire
Tests: There are 6 pre-tests and 6 post-tests. (One of them was actually the overall total of the other 5 tests.) The division of students in high, average & low was also based on the pre-test.
Questionnaire: It consisted of 12 scales. (3 scales were aggregates of some of the other scales.) The questionnaire was given to the students once only, after the experiment.
It seems that I should use MANCOVA because there are two dependent variables, one of which is a repeated measure (tests).
However, the analysis seems very complex because there are a large number of variables (6 tests & 12 scales) and I'm not sure how to go about doing it in SPSS. When I go to Analyze => GLM => Multivariate, I'm not sure what to do next.
