Creswell (2007) describes two approaches to ethnography. In realist ethnography the more traditional approach, the researcher tries to provide an objective account of the situation, typically from a third-person point of view. Standard categories are used. and factual information and closely edited quotes are presented as data.The researcher's interpretation occurs at the end. In critical ethnography, the researcher takes an an advocacy perspective and has a value-laden orientation. The researcher is advocating for a marginalized group, challenging the status quo, or attempting to empower the group by giving it voice.
