independent variable
independent variable Within a particular study, analysis, or model, the independent (or explanatory) variable is the social element whose characteristics or variations shape and determine the dependent variable: for example, the age of marriage can help explain the likelihood of divorce. In an experimental situation, independent variables can be systematically manipulated, so that the effect on the dependent variable can be observed. Whether a variable is treated as dependent or independent is determined by the theoretical framework and focus of a study, but independent variables must precede the dependent variable, and should have causal powers. See also CAUSAL MODELLING.
