When designing an experiment, you need to consider three types of variables. The independent variable is changed by the experimenter in the design of the experiment. This variable is sometimes called the
"manipulated variable." The dependent variable is what changes as a result of the change in the inde-
pendent variable. This variable is sometimes called the responding variable." In some cases more than
one dependent variable is considered. The third category of variables is controlled variables. These are variables that you think may change the outcome of the experiment, but since they are not being studied,
they need to be kept constant in each trial.
