Methods of Observation :There many methods of observation. Any one of them can be used by the researcher. These are as: 1. Structured or Unstructured Observation : This observation is used when the research problem has been formulated precisely and the research is told to observe the area of study. The researchers are asked to record their observations. On the other hand unstructured observation implies that the researchers are free to observe whatever they feel relevant and judicious.
2. Disguised Observation : Here the subject or information do not known that they are being observed. This is preferred as it is feared that people may behave differently when they known that somebody is observing them it is difficult to completely disguise an observation. It poses and ethical question of its desirability when those who are being observed are kept in dark.
