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.
Detailed explanation-2: -An experimental group in a scientific experiment is the group on which the experimental procedure is performed. The independent variable is changed for the group and the response or change in the dependent variable is recorded.
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: -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.
