What is an experimental control?
A group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment. cw: An experimental control may be the control group. In general, the experimental control is something that allows you to say that the treatment effects on the experimental group are due to the treatments, rather than anything else.
In a controlled environment which group experience the test?
Experimental group
What is the difference between a control group and an experimental group?
Control groups do not test the variable or action. They are a constant comparative base. The experimental group has one different variable. They two are compared to see what affect (if any) the variable has. The control group is not exposed or subjected to what they're testing. The experimental group is. For example, a control group and an experimental group may each consume the same foods, on the same schedule. The experimental group would also receive a nutritional supplement, to see if it had any beneficial effect. This would ideally be the only major difference in the two groups.
What is a control in a scientific experiment?

Group A (The experimental group) is given the real drug, and Group B (The control group) is given a fake drug (placebo) to compare results.
What is the group that receeives the experimental treatment?
