What is variables used for previous literature in literature review
Variables used for previous literature in a literature review refer to the specific elements or concepts that were examined or measured in the studies included in the review. These variables are usually identified in the methods or results sections of the reviewed studies and are summarized and analyzed in the literature review.
The variables used can vary depending on the research topic and the focus of the literature review. They can include both independent variables (factors or conditions that are manipulated or observed to determine their effect on other variables) and dependent variables (outcomes or criteria that are measured or observed to assess the effects of independent variables).
For example, in a review on the effects of exercise on mental health, the variables used in the previous literature might include the type and duration of exercise (independent variables) and measures of mental health outcomes such as anxiety or depression levels (dependent variables).
In addition to independent and dependent variables, other types of variables commonly found in literature reviews include control variables (variables held constant or controlled for in order to isolate the effects of the independent variables), moderating variables (variables that influence the relationship between the independent and dependent variables), and mediating variables (variables that explain the relationship between the independent and dependent variables).
Overall, the variables used for previous literature in a literature review are essential for understanding the research focus, methodology, and findings of the reviewed studies, as well as for identifying trends, patterns, or gaps in the existing literature.
