AP PSYCHOLOGY

Detailed explanation-1: -In a scientific study, a control group is used to establish causality by isolating the effect of an independent variable. Here, researchers change the independent variable in the treatment group and keep it constant in the control group. Then they compare the results of these groups.

Detailed explanation-2: -The group in a clinical research study that receives the drug, vaccine, or other intervention being tested. Interventions may also include medical procedures (such as radiation therapy and surgery), medical devices, behavior changes (such as diet and exercise), education programs, and counseling.

Detailed explanation-3: -An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study. Independent variables are also called: Explanatory variables (they explain an event or outcome)

Detailed explanation-4: -A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable’s effects on the experiment and can help rule out alternative explanations of the experimental results.

Detailed explanation-5: -An experimental group is a group in a scientific experiment that gets exposure to the independent variable. The researcher changes the independent variable to see the impact on the dependent variable they’re testing.
