Define what the literature review is and its relevance in a research proposal

A literature review is a comprehensive survey of scholarly sources on a specific topic. It is a critical and in-depth evaluation of previous research. It is a summary and synopsis of a particular area of research, allowing anybody reading the paper to establish why you are pursuing this particular research program.

The relevance of a literature review in a research proposal is multi-fold:

1. It provides a context for your study, and helps readers understand the background and significance of your research question.
2. It helps you identify key themes and trends in the field that are related to your research, which can guide the development of your research question and objectives.
3. It allows you to demonstrate your familiarity with previous work in the field and how your proposed research can contribute to new knowledge or a new understanding of the subject matter.
4. It can help you identify methodologies and research techniques that have been used in the field, which can be useful in designing your own research methods.
5. It can help you identify gaps in the existing literature, which your research aims to fill.

In summary, a literature review is a crucial component of a research proposal as it provides a foundation for understanding the research problem, its context, and the methodologies that can be used to investigate it.
