2. Natural Observation: Natural observation involves observing the behaviour in a normal setting and in this type of observation, no efforts are made to bring any type of change in the behavior of the observed. Improvement in the collection of the information and improvement in the environment of making an observation can be done with the help of natural observations.
4. Direct and Indirect observation: With the help of the direct method of observation, one comes to know how the observer is physically present in which type of situation is he present and then this type of observation monitors what takes place. Indirect method of observation involves studies of mechanical recording or the recording by some of the other means like photographic or electronic. Direct observation is relatively more straight forward as compared to the indirect observation.
5. Participant and Non Participant observation: Participation by the observers with the various types of operations of the group under study refers to the participant type of observation. In participant observation, the degree of the participation is largely affected by the nature of the study and it also depends on the type of the situation and also on its demands.But in the non participant type of observation, no participation of the observer in the activities of the group takes place and also there occurs no relationship between the researcher and the group.
6. Structured and Unstructured observation: Structured observation works according to a plan and involves specific information of the units that are to be observed and also about the information that is to be recorded. The operations that are to be observed and the various features that are to be noted or recorded are decided well in advance. Such observations involve the use of especial instruments for the purpose of data collection that are also structured in nature. But in the case of the unstructured observation, its basics are diametrically against the structured observation. In such observation, observer has the freedom to note down what he or she feels is correct and relevant to the point of study and also this approach of observation is very suitable in the case of exploratory research.
7. Controlled and Non Controlled observation: Controlled observations are the observations made under the influence of some of the external forces and such observations rarely lead to improvement in the precision of the research results. But these observations can be very effective in the working if these are made to work in the coordination with mechanical synchronizing devices, film recording etc. Non controlled observations are made in the natural environment and reverse to the controlled observation these observations involve no influence or guidance of any type of external force.
