- What is the function of a control in an experiment?arrow_forwardThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.arrow_forwardWhat is control group? Explain the purpose of a control in an experiment.arrow_forward
