If I am looking for a relationship between several different variables (personality characteristic, attachment, eating pathology) does it matter that they have all been measured on different scales?
For example - some give a score out of 20, some of the sub scales give scores out of 5 and so on. Is there anything I need to do before conducting the analysis?
