Why is it important for researchers to use a control group in a scientific study? only when participants listen carefully and follow precisely the instructions of the experimenter will the study be controlled and thus yield valid scientific conclusions. when a researcher manipulates the control group, it is always under carefully scrutinized and supervised conditions, thereby increasing the validity of the study. it is important to show that between two groups that were similar from the beginning of the study, the one that received the manipulation is the one that changes. the control group receives the experimental manipulation or intervention and is therefore the reason one would conduct a scientific study in the first place?

Researchers must utilize a control group in a scientific study because it is important to show that between two groups that were similar from the beginning of the study, the one that received the manipulation is the one that changes. Note that the control group is the group in the experiment that does not receive manipulation by the experimenter and is thus used as basis for how the other test subjects changed.
