In an experiment, the control group is used for comparison to determine if the treatment worked or not.
Step-by-step explanation:
In an experiment, the control group can be used for comparison to show if the treatment worked or not.
The control group is a group that does not receive the treatment being tested, while another group, called the experimental group, does receive the treatment. By comparing the results between the two groups, it becomes possible to determine the effectiveness of the treatment.
For example, if a new medication is being tested, the control group would receive a placebo (inactive substance) or an existing medication, while the experimental group would receive the new medication. This allows researchers to evaluate the impact of the new medication by comparing the outcomes between the two groups.
