Quizplus · Accepted Answer

A confounding variable is a type of variable that is not controlled in an experiment and can affect the outcome of the experiment in unexpected ways. It is not the independent variable, which is deliberately manipulated by the experimenter. It is also not the dependent variable, which is the outcome measure being studied. Controlled variables are variables that are deliberately kept constant in an experiment.
