When I was in school and had a Human Resources class the teacher had us take a survey like the one in this volume. The results are plotted on an x-y axis and where your line is on the axis shows not only what category you fall into but how you relate to the other categories.
Do you happen to know which one I'm thinking of? I'm sorry I don't have a name for it. It might be fun for this group. I have it at my parent's home and I can get it when I go home at Christmas if you don't know this particular survey.
