The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.

experimental control
The control group serves as a baseline for comparison with the experimental group. It does not receive the experimental treatment or intervention, allowing researchers to measure the effect of the treatment by comparing the results of the control group to those of the experimental group.
The treatments can be compared to each other instead of to a control
control group
The experimental protocol describes and determines materials, equipment, and procedures.
The experimental investigation is realized by experiments which are rationally interpreted.
When doing experiments you have to have a control group and an experimental group. The control group is not given a drug (for example), while the experimental group is. This will show (later on) if the drug had a real effect. Sometimes the control group will be given what is called a placebo. This looks just like the drug that the experimental group is given, except it has nothing in it.
Experiments are the only type of research from which conclusions can be made. This is because they are conducted in controlled settings and include a control group.
The experimental investigation is realized by experiments which are rationally interpreted.
In an experimental design comparing two groups in which one group gets one treatment and another group gets a second treatment, the experimental group is the group with the "different" treatment. The control is the "usual" treatment; the experimental group gets the "new" treatment. Of course, things get complicated with more complicated "experiments."
Experimental physics. Only with experiments come a theory:)
