Many of my students have asked me what the difference is between a case study and an ethnography, an understandable question as these methods are similar. Conducting an ethnographic study may, on the surface, appear to be very similar to case study research but it is the extent to which the researcher is immersed in the context that is the real and most obvious difference. The focus of ethnography is to describe and interpret a cultural and social group, whereas the focus of case study is to develop an in-depht analysis of a single case. A case study site is usually visited at regular intervals to engage in data collection that can be largely predefined, whereas ethnography demands prolonged engagement within the context (Creswell, 1998).
