Answer:
False
Explanation:
Ethnography is a type of study that is concerned with getting a detailed account of a culture and social life of a particular system, by harvesting multiples of detailed observations of what people do in that particular system or social setting. Ethnography makes use of participant observation, surveys and face-to-face interviewing to get such information. It doesn't involve clustering people to get in-depth answers to specific questions.
Therefore the primary data collection method entails having 10 to 12 people interviewed for 60 to 90 minutes to get in-depth answers to specific questions is not ethnography
