Statistics QUESTION help appreciated?

Hi there, I have a data I obtained of 280 students that were surveyed. The demographic variables were that there were males and females asked (1=female, 2=male). Whether they were single (1), married (2) or in a long term relationship (3). And the numeric variables were level of happiness, optimism and satisfaction of life with high numbers representing high levels of well being. My question is that I want to choose something to study from this, such as whether single females are happier than married men or something like that - something relatively easy as I'm not great at stats - and show it in some statistics but I'm not quite sure at this stage. any ideas or suggestions are much appreciated!!
