What is a control treatment examples?
Example of a Control Group\n\n Assume you want to test a new medication for ADHD.

The group who takes the placebo would be the control group.
What does control treatment mean?
A good design for evaluating the effect of a single treatment will, therefore, always include a second treatment, called a control or control treatment, for comparison purposes. In some experiments, the control is the treatment in current use, and in other experiments it is the 'absence of a stimulus.
What is the purpose of a control treatment in an experiment?
Beyond the methodology, controlling an experiment is critically important to ensure that the observed results are not just random events; they help scientists to distinguish between the signal and the background noise that are inherent in natural and living systems.
