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 and show it in some statistics but I'm not quite sure at this stage. Any guidance or advice is much appreciated. thx
