Answer:
The collection of life histories.
Explanation: An ethnographer is a researcher who studies a particular group of people in an effort to understand them and describe them to others as best they can.
Ethnography entails examining the behavior of the participants in a given social situation and also understanding group members' own interpretation of such behavior.[1] Dewan (2018) further elaborates that this behavior may be shaped by the constraints the participants feel because of the situations they are in or by the society in which they belong. Ethnography, as the presentation of empirical data on human societies and cultures, was pioneered in the biological, social, and cultural branches of anthropology, but it has also become popular in the social sciences in general—sociology,[2] communication studies, history—wherever people study ethnic groups, formations, compositions, resettlements, social welfare characteristics, materiality, spirituality, and a people's ethnogenesis.
