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?
Do you only have 10 data points or is there over plotting of points? Are the data ratings so that the distance between "numbers" is not necessarily uniform?
Maybe you have to deal with categorical variables in which case you might find this discussion useful:
