I am conducting an ethnographic study where I collected data via participant and semi-structured interviews. At the beginning of the research, the ratio of male and female participants was OK. However, when I came back for my interviews (after 6 months) there was only 1 female to interview (before they were 6). My supervisor thinks that this is not a meaningful observation. How can I convince the readers that it is meaningful?
the study is conducted in the context of a restaurant
I would really appreciate your help. Thanks
