Obtrusive observation technique

Obtrusive or participant observation

Here the researcher joins the individual or group being observed. Everyone knows they are being observed and by whom in this forward and open method. Examples of participant observation include the following: joining police patrols in their cruiser and observing police activity as they make rounds; spending a month on a North Atlantic oil rig observing the lives of the oil workers. Ethnographic researchers and anthropologists use this form of observation research; their written observations are the field notes. Observation research, whether obtrusive or non-obtrusive, involves some of the most difficult research techniques. Observers require extensive training in observation methodologies, and, in particular, how to report their findings.
