Regression focuses on predicting values of a dependent variable based on the values of independent variable(s). One of the reasons I really enjoy reading students' discussion posts is that you often raise ways of thinking about situations that I have never considered (i.e. a student once related the impact of a bartender's personality on his/her productivity - bar patrons having a good time spend more money - and this made me think about how employees' personalities, attitudes, etc. likely impact productivity of themselves and fellow employees across a variety of industries). Please tell us about a situation from your life experience (work or otherwise) where you believe a dependent variable is affected by an "unexpected" independent variable. You don't need to do a regression or provide definitive proof of the relationship, just make your case for why you believe there is a relationship.
