AP PSYCHOLOGY

Detailed explanation-1: -A control group is a group in the experiment which a variable is not being tested, such as a test subject that does not receive any treatment. Control groups serve as important benchmarks to compare the results of the experimental group, or the group that is being experimented on.

Detailed explanation-2: -Control groups in experiments 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-3: -Negative control group: In this type of control group, the participants are not given a treatment. The experimental group can then be compared to the group that did not experience any change or results.

Detailed explanation-4: -In experimental research, some subjects are administered one or more experimental stimulus called a treatment (the treatment group ) while other subjects are not given such a stimulus (the control group ).

Detailed explanation-5: -A control group is used as a comparison for the experimental group. The control group is the group in an experiment that does not receive any change in the variable. This group is left as natural as possible and used as a control to see if there is a change from the normal results.
