What is a key feature of non-participant observation?

A key feature of non-participant observation is that the researcher maintains a distance from the group being studied. This approach allows the researcher to observe the behaviors, interactions, and dynamics of the group without becoming involved in their activities. By keeping this distance, the researcher can gather data in an unobtrusive manner, which helps to minimize any influence they may have on the participants' natural behavior. This type of observation is useful for obtaining a more authentic understanding of social interactions and norms, as it allows the researcher to focus on the context and environment while remaining an outside observer.

In contrast, the other choices illustrate aspects of research methods that do not fit with non-participant observation. For example, interacting heavily with participants or participating in the group's activities would suggest a more engaged approach, such as participant observation, which is fundamentally different from maintaining a non-involved stance. Additionally, deliberately changing group dynamics would imply interference that can distort the authenticity of the data collected, which is contrary to the objectives of non-participant observation.
