non-participant observation research method

Explanation:

In non-participant observation studies, Greg is not part of the group being studied. He decides in advance precisely what kind of behaviour is relevant to the study and can be realistically and ethically observed. He observes the way students talk to each other. He makes notes on the words used, the atmosphere of the school and the way the students present themselves to each other.The observation can be carried out in a few different ways. Observation does not only include noting what happened or was said but also the fact that a specific behaviour did not occur at the time of observation.
