That's new to me. Not that I can't figure it out, but a little direction may help. Let me give some more detailed information.
I have Male/Female (categorical) and I know that there is a significant difference on one of my 5 (continuous) IVs. Specifically, the IV has to do with the likelihood that the individual will employ a "physical" style of relationship initiation. I have a strong intuition about WHY there is a significant difference, but, of course, I need to establish the nature of the relationship objectively before I can say "males are more likely to employ physical styles" and discuss it further (even though this is already established in the literature, I need to speak specifically concerning my sample).
With gender identity, Tukey HSD tells me the nature of the relationship (positive or negative), so I can base my "masculine and androgynous individuals are more likely to employ physical styles" off of some objective results. Something that tells me, not just that there is a significant difference, but what that difference means; the direction (positive or negative) of that relationship.
I understand that you are probably telling me that - and thank you very much. I'm only offering the specifics so that any subsequent responses are better informed. Also, I have to admit, I do not know what box plots or error bars are and I'd like to keep this as simple as possible. Nothing I've learned so far has been overwhelming, so I'm ready to tackle whatever. But, is there a third or fourth alternative that will do what I need?
Oh, and I'm using SPSS. On a scale of 1-10, I rate myself a 3 with SPSS... but, not being a 10, I'm probably not qualified to rate myself. :-/
Thanks so much!
