Giaztyne Lopez Dumalaon it depends on your research question, problem statement, research gap, and available secondary sources of your research area. And finally the motivation of your supervisor(s), his depth of knowledge, and his philosophy. I found most of the supervisors think research/thesis from his/her side may be from their philosophical standpoint, which is difficult for the students sometimes to overcome if they don't help the students by giving enough time in tutorial with freedom.
However, in primary research questionnaire survey, key informants' interview ( KII), Focus Group Discussion ( FGD), and Case study are the popular methods of qualitative research on the other hand, in the case of secondary research, if connected to previous research works are available, then you can think about content analysis. For your maximum output and standard argument, you can go for research triangulation finally which may be a blending of primary and secondary research. But I think triangulation works for senior/experienced people who must have insightful knowledge of research and the power of arguments and pieces of evidence. Thank you very much. Please be connected with me if you need further help, though I am packed up with my work. Best of luck.
In this case, a case study approach would allow for an in-depth exploration of the experiences of Filipina beauty pageant joiners, specifically focusing on how skin stratification and height measurement affect their feelings of psychological disempowerment. It could involve conducting interviews, focus groups, and participant observation of beauty pageant events. Additionally, using a case study approach allows for the collection of rich and detailed data, which can help to generate a more nuanced understanding of the research question.
