Control Groups

A control group, is a scientific experiment in which the factor being tested is not applied so that it may serve as a standard for comparison against another group where the factor is applied. A control group is used to make conclusions more accurate. This being, because both the control and other experimental groups are to the same conditions, apart from being tested. An example of a control group, would be if two of the same animal are being tested, one gets a special type of medicine, and the other one doesn't. The one that doesn't would be the control animal.
