Say you are doing an experiment to see if sugar effects how a child behaves. You have two children (or groups of children).
Control - The control group would be the children who receive no sugar in their diet.
Variable - The variable in the experiment would be the children you feed candy or sugar to.Biology- what does experimental variable and control variable mean?
In the design of experiments and data analysis, control variables are those variables that are not changed throughout the trials in an experiment because the experimenter is not interested in the effect of that variable being changed for that particular experiment. (In other words, control variables are extraneous factors, possibly affecting the experiment, that are kept constant so as to minimize their effects on the outcome.) An example of a control variable in an experiment might be keeping the pressure constant in an experiment designed to test the effects of temperature on bacterial growth.
In a scientific experiment, the controlled variable never changes; it is the same for every setup. For example, in an evaporation experiment, the area must be the same.
You can also check the Ivan Pavlov and his theory on classical conditioning. It may explain the control and experimental variable better.
Good Luck!
