I am currently doing research with an independent variable (four treatment groups), a continuous dependent variables, 5 control variables, and 2 continuous moderators. I figured out that I needed to do an ANCOVA analysis with the 5 control variables as covariates and the treatment groups as factor. I just cannot figure out how I can include the moderating variables into the analysis. Do I put them into the analysis as covariates (moderator1 & moderator1*treatment & moderator2 & moderator2*treatment) or should I do this differently, for instance not including the interaction variables?
