AP PSYCHOLOGY

Detailed explanation-1: -An experimental group is a test sample or the group that receives an experimental procedure. This group is exposed to changes in the independent variable being tested. The values of the independent variable and the impact on the dependent variable are recorded.

Detailed explanation-2: -An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be identical in all other ways.

Detailed explanation-3: -Independent Variable = What the investigator manipulates; the particular treatment or condition the. investigator is most interested in the effects of. Dependent Variable = What is measured or observed; the “data” collected in the experiment. Experimental Group = Those participants exposed to the independent variable.

Detailed explanation-4: -Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

Detailed explanation-5: -The independent variable, also known as the experimental treatment, is the difference or change in the experimental conditions that is chosen by the scientist (the cause).
