It is true that the experiments are designed so that the control group differs from the experimental group by one key variable.
In a scientific experiment, a control group is a group that is separated from the rest of the experiment and where the independent variable being evaluated cannot affect the outcomes.
This isolates the effects of the independent variable on the experiment and can aid in ruling out alternative explanations for the experimental results.
An experimental group is made up of participants who are subjected to a specific manipulation of the independent variable. These are the people who get the treatment of interest.
