This document discusses ethnography as an invaluable research method. It defines ethnography as the scientific description of peoples and cultures with their customs, habits, and differences. Ethnography uses both qualitative and quantitative methods in a holistic and interpretive way to study cultural systems from emic and etic perspectives. It is a flexible and iterative process that relies heavily on fieldwork through daily recording of field notes. Ethnography presents case studies of host populations in human contexts. It implies formulating questions, collecting and testing data, and drafting conclusions while leaving room for doubt. Ethics in research require avoiding falsification and acknowledging others' work to prevent plagiarism.
