Detailed explanation-1: -The correct answer is B). The control group is treated exactly the same as the experimental group except that the experimental treatment is not applied.
Detailed explanation-2: -Explanation: In a controlled experiment all variables are kept the same, except for the one being tested, which is called the experimental variable, or independent variable . This group is the experimental group . The group that is not affected by the experimental variable is the control group .
Detailed explanation-3: -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.
Detailed explanation-4: -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-5: -Definition: Control Group In a scientific experiment, an independent variable remains constant in the control group and changes in the treatment group. These groups help establish a cause-and-effect relationship between the dependent and the independent variable.
