Yes, that is correct. In a controlled experiment, a control group is used as a basis of comparison for one or more experimental groups. The control group is typically treated identically to the experimental group(s) with the exception of the independent variable being studied. The independent variable is the factor that is being manipulated in the experiment, and the dependent variable is the outcome being measured.
By comparing the results of the control group with those of the experimental group(s), researchers can determine whether any observed effects are due to the independent variable or simply due to chance or other factors. This helps to ensure that any observed effects are not simply a result of random variation or other external factors.
Controlled experiments are widely used in scientific research, particularly in fields such as medicine, psychology, and biology, where researchers need to determine the effects of specific interventions or treatments on various outcomes.

Yes, a controlled experiment compares results from a control group with results from experimental groups. A control group is a group of participants who do not receive any treatment, while the experimental groups receive different treatments. The results of the experiment are then compared to the results of the control group to determine the effectiveness of the treatments.
In a controlled experiment, the experimenter divides the subjects into two groups: a control group and an experimental group. The control group is not exposed to the treatment that is being tested, while the experimental group is. The experimenter then measures the results of the treatment in both groups and compares them to see whether or not the treatment had an effect. The control group serves as a baseline or reference group, allowing the experimenter to determine if any changes observed in the experimental group are due to the treatment being tested or due to other factors. By comparing the results of the control group to those of the experimental group, the experimenter can determine if a particular treatment is effective or not.
