Introduction
A literature review is an essential part of the research process, and it is a critical step in designing a study. A literature review is essential for a researcher before designing a study. By evaluating and analyzing the existing research on a particular topic, the researcher can gain insight into the topic, identify gaps in knowledge, and draw logical conclusions. A literature review can also provide a background for the research question and enable the researcher to form a hypothesis. This essay will explain why a literature review should be undertaken and how the information obtained can help form a hypothesis.
The Role of a Literature Review in Research
First, a literature review allows the researcher to gain an in-depth understanding of the topic and any related research that has been conducted. Perusing the literature can give a comprehensive view of the theme and an exhaustive examination of related studies and theories (Snyder, 2019). This can assist the researcher in detecting any unaddressed gaps in the literature that can be filled with their research.
Second, the information gathered in a literature review can help the researcher develop a hypothesis or theory about the research question. A hypothesis is fundamental to any research study because it serves as a basis for assessing the research question (Snyder, 2019). Through a literature review, it can be ascertained what the current state of knowledge is and what areas still need to be examined. This helps to form a hypothesis that is grounded in the existing literature and can be supported through empirical data.
Finally, the literature review should come before designing the study and forming the research question because it provides the foundation for the research project. Reviewing the literature and understanding the existing research in the field is crucial before deciding on a research question and designing the study (Snyder, 2019). This ensures the research is relevant and current and fills a knowledge gap.
Conclusion
To summarize, the research process is not complete without a thorough literature review. This review helps the researcher gain extensive insight into the topic, form a hypothesis, and craft the research question. Subsequently, conducting the literature review before beginning the study and formulating the research question is imperative for a successful research outcome.
