Verified step by step guidance

Understand the role of different components in an experiment. The dependent variable is what you measure in the experiment, the independent variable is what you change, and the experimental group is the group that receives the treatment.

Identify the purpose of a control group. A control group is used as a baseline to compare the results of the experimental group. It does not receive the experimental treatment.

Recognize that the control group helps to isolate the effect of the independent variable on the dependent variable by providing a standard for comparison.

Consider why a control group is necessary. It helps to ensure that the results are due to the independent variable and not other factors.

Conclude that in an experiment, the control group serves as the point of comparison for the results, allowing researchers to determine the effect of the independent variable.
