Explanation: In research, a variable is a phenomenon or event that can be measured, observed, or manipulated. Variables can take different values or states, and they are the focus of investigation in research studies. Depending on their nature, variables can be categorized as independent variables (which are manipulated or controlled by the researcher) and dependent variables (which are observed or measured to assess the effects of the independent variables). Understanding variables is fundamental in designing and conducting research, as they form the basis for hypothesis testing and data analysis.
