EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -The two groups typically are a treatment group and a control group. The treatment group, also known as the experimental group, receives the treatment that the researcher is evaluating. The control group, on the other hand, does not receive the treatment.

Detailed explanation-3: -The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is “controlled” or held constant in the control group.

Detailed explanation-4: -Specifically, control groups are the customers you are targeting with a particular campaign who will not receive that campaign. The counterpart of control groups is test groups which are the customers you are targeting that will receive that specific campaign.

Detailed explanation-5: -In experimental research, the control group is the group of participants that do not receive the experimental treatment and serves as the standard for comparison.
