Question: Please can you help me understand which statistical test to use? I have one predictor variable and three outcome variables (they are all continuous variables as they are measured on likert scales). At first I thought MANOVA, but for MANOVA the predictor variable must be categorical and mine is not. For multiple regression, there must be more than one predictor variable and I only have 1. I am looking at how changes in the predictor variable change outcome variables but also want to understand relationships between outcome variables so would rather not do a simple correlation/linear regression. Any help would be so useful thank you - I am in early stages of my research so will be coming to you for further support over the next few months if you are willing to help.   Edit
