Detailed explanation-1: -A control group is a group separated from the rest of the experiment such that 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-2: -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: -Listen to pronunciation. (kun-TROLE groop) In a clinical trial, the group that does not receive the new treatment being studied. This group is compared to the group that receives the new treatment, to see if the new treatment works.
Detailed explanation-4: -Dependent Variable = What is measured or observed; the “data” collected in the experiment. Experimental Group = Those participants exposed to the independent variable. Control Group = Those participants treated just like the experimental group EXCEPT they are not.
