control roup

Hi PhoebeDychinco, that is what I am thinking as well. Initially, I misunderstood the limitation someone had mentioned, which is in our study, we lack of a control group. I completely agree with you, in order to find some causality between variables such as occupation and gender, experiment need to be designed. Also in designing a comprehensive research, the combination of LOST data is best persuasive.
