Thanks for your response; with so little information you clearly understand what I’m trying to do. However I think now that I need to do a subsequent analysis after ANOVA. All my results were significant. I think I want to do a kind of multiple comparison to see which level of the independent variables had the greatest effect. Am I along the right track and if so how do I apply this using SPSS. I hope you don’t mind but I emailed you my interpretation of the results and would really appreciate it if you could advise me further. Thanks again
