Which group can be measured against the experimental group in an experiment?

In an experiment, the control group serves as a benchmark for comparison against the experimental group. The experimental group is exposed to the treatment or condition being tested, while the control group is kept under standard conditions without the treatment. This allows researchers to determine if the changes observed in the experimental group are a result of the treatment or other factors.

The control group is essential for establishing causality and validating the results of the experiment. By having a control group, scientists can measure the effect of the independent variable on the dependent variable effectively. This comparison helps to isolate the effects of the treatment being studied and supports more accurate conclusions regarding its efficacy or impact.
