Types  of Observation:

Types of observation relate  to  the  observer-observed relationship. It has been described as "concealment and participant", "concealment and non- participant", "no-concealment and participant" and "no-concealment and non-participant" as diagrammatically shown  in  Figure.  

"Non-concealment"  and "Concealment"  refer to whether the observer makes his intentions known  to the persons observed or not, whereas "participant"  and "non-participant"  refer  to  the role of observer; that is, whether the observer  is  a part  of the social setting or makes the observation from periphery of a social setting. The instruments used for the technique can be unstructured e.g.  logs and  field notes, Anecdotes or can be  structured e.g.  "Logs  and Field Notes":  Logs  is  a record of events and conversations and usually is maintained on  a daily basis by  field worker.  

• "Field notes"  may  include  daily  log  but  tend  to be  much  broadel;  more analytic, and  include  more  intelpretation  than  more  listing of occurrences. "Anecdotes":  Anecdotes focus on behaviour of particular interest.
• Anecdote typically  selects specific kind  of events and behaviours for observation beforehand. The observer objectively, and accurately records the observation.
• "Checklists": It  is  a tool used  for structured observation where phenomena are recorded by  putting a tally against a particular behaviour, event or characteristic depending upon  its presence or absence (Refer Block 2). When  developing a checklist researcher must  list all the expected behaviours related to  the vaiiable being measured. So  that alr relevant behaviours  in  the subjects will correctly' be identified.
