An experiment has to have a varible, if it doesn't that it's probably and engineering experiment or robotics. I think its called a "control"
The dependent variable is the variable that can change in an experiment.
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.

The dependent variable is the variable that can change in an experiment.
A control group in an experiment is a part that is maintained without change in order to provide a comparison for the part of the experiment containing the variable. This helps researchers determine if any observed effects are due to the variable being tested or other factors.

The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
In an experiment, the variable that is held constant is called the control variable. This variable is not changed or manipulated during the experiment in order to isolate the effect of the independent variable on the dependent variable.
