.
The responding variable (also called dependent variable) is the variable that a scientist observes to change while conducting a scientific experiment. The responding variable depends on the independent variable (also called manipulated variable). When the independent variable is changed by the scientist, its effect on the responding variable is usually observed and recorded. Responding variables can be observed (such as taste) or measured (such as length) in an experiment.
