Why Reviewing Previous Studies Matters in Research

Previous studies are an essential part of any scientific research plan, as they provide researchers with a strong theoretical background that helps them develop their research in an organized manner. Reviewing previous studies allows the researcher to have a deeper understanding of the field they are studying, which helps them identify research gaps and avoid duplicating previous research.

In this article, we will discuss in detail the importance of reviewing previous studies in a research plan, how to search for and select them, as well as how to use and write them in a professional academic manner.

What Are Previous Studies in a Research Plan?

RepresentPrevious studiesa collection of research and scientific sources that researchers in various fields have relied upon to support their ideas and formulate new research based on available knowledge. These studies are considered a major part ofthe scientific research planas they provide the researcher with a solid knowledge base, helping them tounderstand developments in the field, identify research gaps, and formulate the research problem in a scientifically accurate manner.

Definition of Previous Studies

Refer toprevious studiesas a collection of research and scientific literature that have addressed a similar or related topic to the current research. These studies may include scientific articles, master’s and doctoral theses, research reports, and specialized books.

The Importance of Previous Studies in Scientific Research

Previous studies play a pivotal role in scientific research, as they provide the researcher with a knowledge background that helps them understand developments in the topic and guide their study in a more accurate and effective manner. Theobjectives of reviewing previous studiesare as follows:

1. Providing a Theoretical Background for the Research

Reviewing previous studies helps in forming a comprehensive understanding of the concepts and fundamental principles related to the topic, which contributes to establishing a strong theoretical framework that supports scientific research.

2. Identifying Research Gaps

Reviewing previous research helps uncover aspects that have not been studied or points that have not been addressed in depth in previous studies, which provides the researcher with an opportunity to make a new scientific contribution.

3. Guiding the Formulation of the Research Problem and Its Questions

When reviewing previous studies, the researcher can develop their own research problem based on issues that still need further study, and thus formulate clear and specific research questions.

4. Developing Research Hypotheses

By analyzing the results of previous studies, the researcher can identify general trends in the topic, which helps in building strong hypotheses based on proven scientific foundations.

5. Supporting Research Credibility and Enhancing Its Reliability

When the researcher relies on reliable scientific sources, their research becomes stronger and more credible, proving that it is built on previous scientific studies rather than just personal conclusions.

6. Benefiting from Previous Research Methodologies

Previous studies provide insight into the different research methods used by other researchers, which helps in selecting the appropriate methodology for the new study.

7. Avoiding Repetition of Previous Research

Reviewing previous studies enables the researcher to verify whether their topic has already been researched, helping them to avoid unnecessary repetition and focus on adding new value.

8. Improving the Quality of Scientific Research

Reviewing previous studies helps in developing scientific research to be more accurate and comprehensive by benefiting from the recommendations and results reached by previous research.

9. Facilitating Data Analysis and Scientific Comparisons

When conducting research, data available in previous studies can be used to compare with new results, which helps in providing a more accurate and objective analysis.

10. Providing a Reference Framework That Helps Future Researchers

When reviewing previous studies thoroughly, future researchers can use the available results and resources to develop their own research, contributing to the advancement of scientific knowledge.
