What is independent variables?
Answers
Explanation:
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Independent variables are controlled inputs. Dependent variables represent the output or outcome resulting from altering these inputs.
Of the two, it is always the dependent variable whose variation is being studied, by altering inputs, also known as regressors in a statistical context. In an experiment, any variable that the experimenter manipulates can be called an independent variable. Models and experiments test the effects that the independent variables have on the dependent variables. Sometimes, even if their influence is not of direct interest, independent variables may be included for other reasons, such as to account for their potential confounding effect.
