I have a conceptual model with 3 regular independent variables and one dependent variable. Next to those three independent variables, I have another moderator variable possible affecting the relationship of two out of three regular independent virables. This makes it actually four independent variables.
I am currently running a three-way anova test with the three regular independent variables. However, I am not sure how to investigate the potential role of the moderator. Actually, I am not sure if I am approaching it in the right way at all.
Review Extremety, Review Breadth and Identity Disclosure are dummy variables (I did an experiment). Product involvement is a continuous variable. Does anyone know what would be a good way to investigate this? Thanks in advance!
