Hey Chloe,
In general you are able to enter multiple predictors (covariates and factors) in one analysis (MANCOVA, in this case), but the order in which you enter them is a conceptual decision, as entering them in the model in different orders answers different statistical/conceptual questions. I hope that is helpful. Please let me know if you have additional questions!
Hi there I am currently working on my dissertation and I need to carry out a MANCOVA. I have 6 dependent variables and 5 covariates. I am just wondering if in SPSS i am supposed to add in all 6 dependents at once followed by fixed factor which for my study is gender (i think thats the categorical IV), followed by my 5 covariates. I guess my question is whether a MANCOVA is one SPSS output or do i have to carry out seperate ones?
