How can variables used for previous literature be written in literature review

Variables used in previous literature can be written in the literature review section by clearly identifying and describing them. Here are some steps to follow:

1. Start by introducing the main topic or research question of the literature review.
2. Provide a brief overview of the studies or articles you are reviewing.
3. For each study or article, identify and explain the variables that were used.
4. Clearly define each variable, providing a concise and accurate description.
5. Include any relevant information about how the variables were measured or operationalized.
6. If there are different levels or types of variables, categorize and explain them accordingly.
7. Discuss any notable findings or patterns related to these variables from the previous literature.
8. Analyze the gaps or limitations in the existing research on these variables, which your own study aims to address.
9. Conclude the literature review section by summarizing the importance and relevance of these variables to your research.

Remember to use proper citations when referring to previous studies or articles, and to critically evaluate the quality and reliability of the research in your literature review.
