What are the variable under study?

The variables under study typically refer to the specific factors or characteristics that researchers are examining in a particular investigation. These can include independent variables, which are manipulated or changed, and dependent variables, which are measured to assess the effect of the independent variables. Additionally, there may be control variables that are kept constant to ensure that the results are due to the independent variables alone. Identifying and clearly defining these variables is crucial for the validity and reliability of the research findings.
