ANATOMY

Detailed explanation-1: -A controlled variable in an experiment is the one that the researcher holds constant or controls. Control variables are the variables or elements that researchers strive to keep constant throughout their research so that they would not influence the outcomes.

Detailed explanation-2: -The independent variable is the one which we (the experimenters) change. The dependent variable is the one which changes because we change the independent variable. A control variable is a variable which is deliberately kept the same.

Detailed explanation-3: -An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable.

Detailed explanation-4: -Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
