Independent variable
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
The independent variable is the one variable that you change in your experiment
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.

the experimental variable is like the independent variable, which is the only thing you can change in a science experiment, and the dependent variables are the things that stay the same.
