Literature review
Literature review is a very important part of the research writing process. It helps the researcher in mainly two ways 1) in collection of data needed for research 2) It helps the researcher to be familiarize with the related work already been done by the other researchers. Different kinds of information are required in research. This can be classified into the following two types of information: 1) Primary data: Primary data are the actual information which is received by the researcher for study from the actual field of research. These data are attained by means of questionnaires and schedules. In some fields primary data are collected through interview and observation methods. The observation method, for collecting primary data, may be both participant and non participant. Such data are known as primary because they are attained by the researcher from the field of research directly and for the first time. Participant observation sometimes unravels such primary data which can not be known by any other means. Literature review doesn’t help too much in collection of primary data. 2) Secondary data: Secondary data are the information which is attained indirectly.
