I'm not sure what class this is for, but in Psychology this would be considered Naturalistic Observation. Hope this helps :)
Answer:
The answer is non-participant observation.
Explanation:
Non-participant observation is a research technique commonly used in social research, it involves watching the research subjects by entering the community but staying separate from the activities that take place. Non-participant observation can be the main technique used in research methods such as ethnography, but it can also be paired with other techniques, like interviews or focus groups.
The main purpose of this technique is to observe the behaviors as they normally occur.
