Ethnographers may begin with a "big net" approach in sampling—that is, they mingle and converse with as many members of the culture as possible. Although they may talk to many group members (usually 25 to 50), ethnographers often rely heavily on a smaller number of key informants, who are highly knowledgeable about the culture and who develop special, ongoing relationships with the researcher. Key informants are the researcher's main link to the "inside." Sampling in ethnography typically involves sampling things as well as people. For example, ethnographers make decisions about observing events and activities, about examining records and artifacts, and about exploring places that provide clues about the culture. Key informants can play an important role in helping ethnographers decide what to sample. Facilitating the recruitment of more participants to the study is not a purpose of choosing key informants.
