EVERYDAY SCIENCE

Detailed explanation-1: -To test if the results will be different, this group has one thing that is different or changed from the other groups in the experiment. The experimental group and the control group should be as similar as possible except for one factor, called a variable, which is changed.

Detailed explanation-2: -The best description of a control group in an experiment is the control group is identical to each test group except for one variable. That variable is the independent variable which is being tested.

Detailed explanation-3: -The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment to control for placebo effect).

Detailed explanation-4: -Control-The control is the group that serves as a standard of comparison. It is exposed to the same conditions as the experimental group, except for the variable being tested. Dependent Variable-A dependent variable is a factor that may change as a result of changes in the independent variable.

Detailed explanation-5: -The difference between the control group and the experimental group is that the control group is not exposed to the independent variable, that is thought to be the cause of the behavior being investigated.
