IMPORTANCE OF LITERATURE REVIEW 1. Identification of a research problem and development or refinement of research questions. 2.

IMPORTANCE OF LITERATURE REVIEW 4. Determination of any gaps or inconsistencies in a body of knowledge. 5. Discovery of unanswered questions about subjects , concepts or problems. 6.

IMPORTANCE OF LITERATURE REVIEW 7. Identification of relevant theoretical or conceptual framework for research problems. 8. Identification or development of new or refined clinical interventions to test through empirical research. 9. Description of the strengths and weaknesses of design, methods of enquiry and instruments used in earlier research work.
IMPORTANCE OF LITERATURE REVIEW 10. Development of hypothesis to be tested in research study. 11. Helps in planning the methodology of the present research study. 12.It also helps in development of research instruments. 13.Identification of suitable design and data collection methods for a research study.
