The chief advantage of participant observation is that in it the observer gets an opportunity to interact with the group regarding various activities of them. He can thus learn the significance of these activities that are actually not open for observation. For example, if an observer participates in a religious ceremony of a tribe, viz. “Chaitra Parba” of Gadaba tribe, he can not only observe different aspects of the ceremony but also clear his doubt by asking various questions to the group members or learn more about that ceremony by discussing with the group in this regard. It is generally easier for the respondent to describe about the event on right occasion than before or after it.
