Hello. I have the following research question "does quality predict satisfaction"? Quality has 3 subdimensions : perivallon (environment), allhlepidrash(communication) and ofelos (benefit).
I figured I should do many linear regressions to check it out. E.g. compare ofelos with satisfaction (ikanopoihsh), allhlepidrash with satisfaction and perivallon with satisfaction. But when i plot the data I see the graph I' ll try to attach... So is it correct to do linear regressions or is something else needed?
