Answer:
Participant observation
Step-by-step explanation:
In anthropology and sociology, the term participant observation refers to a technique that is used to obtain information from a group (usually a community, a different culture) by being part of the community. In other words, the research becomes a participant in the community for a large period of time and lives as a member of this group in order to gain a better understanding of their values, beliefs, traditions, etc.
By becoming part of the group of study they can collect data (making questions for example) but not in a distant manner but actually with a better understanding of the group of study.
Cultural anthropologists often spend a great deal of time in the communities where they conduct research and they ask lots of questions as people work, celebrate, dance, or play games. We can see that they are spending a lot of time in the community and they become part of it, therefore, this is an example of participant observation.
