What is the purpose of a control group in an experiment?
A. To ensure that all variables are held constant
B. To provide a standard of comparison
C. To manipulate the independent variable
D. To observe the effects of the dependent variable
Answer (2)
The primary purpose of a control group in an experiment is to provide a standard of comparison, which allows researchers to determine the effects of the independent variable compared to a baseline scenario. This helps ensure that results are valid and reliable. Control groups are essential in isolating the impact of treatments or interventions. ;
The control group in an experiment serves as a standard of comparison, allowing researchers to determine the effects of the independent variable on the dependent variable. By comparing results from an experimental group to a control group, researchers can identify the true impact of the treatment. This setup ensures more accurate and reliable conclusions from the experiment.
