I am post graduate student. This is my first ever post in the methodspace. I have a confusion about making boundary in case study. I would grateful if you kindly help me with your intellectual effort. My request is related to my dissertation work. I have formulated my research question, ‘what factors appear to influence A level students of Bangladeshi heritage in the UK?’ I am intend to follow case study research approach. But I am bit confused about boundary of case study. If I restrict my research question into subject choice of Bangladeshi heritage, would it be alright as a boundary? I am wondering about another thing, if I include my sample from two different places for example Bangladeshi students from east London and Bangladeshi students from Wales, at that time would it create any problem or gap in my research?
I would be really grateful if you kindly help me overcome this confusion.
