What form of research involves participant observation, interviews, and unobtrusive data collection?

Fieldwork is a key method in cultural anthropology that emphasizes immersion in the community being studied. It involves participant observation, where the researcher engages in daily activities alongside subjects to gain deeper insights into their cultural practices, social interactions, and beliefs. Additionally, interviews provide a platform for gathering personal narratives and understanding the perspectives of individuals within that community. Unobtrusive data collection allows researchers to gather information without influencing the behavior of those being studied, contributing to a more authentic representation.

This combination of methodologies is central to anthropological inquiry, as it seeks rich, qualitative data that captures the complexities of human life. The other options, such as quantitative data, experimental data, and survey research, typically focus on different approaches or types of data collection that do not emphasize immersive engagement or the qualitative nuances that define fieldwork in cultural anthropology.
