1. To establish the current state of knowledge: One of the primary purposes of a literature review is to summarize and synthesize existing research on a particular topic or research question. By reviewing the existing literature, researchers can identify gaps in knowledge, inconsistencies in findings, and areas in need of further study.
2. To provide theoretical and conceptual framework: A literature review helps to establish a theoretical and conceptual framework for the research study. It allows researchers to situate their study within the larger context of existing knowledge and theories in the field, helping to guide the development of research questions and hypotheses.
3. To identify methodologies and methods: Literature reviews help researchers identify and evaluate different methodologies and methods that have been used in previous studies. By examining how other researchers have approached similar research questions, researchers can make informed decisions about the most appropriate research design, data collection methods, and analysis techniques for their own study.
4. To support the relevance and significance of the study: By providing a comprehensive overview of existing research and theoretical perspectives, a literature review helps to support the relevance and significance of the study. It demonstrates the importance of the research question and helps to justify why the study is worth pursuing.
