This educational material explains how to distinguish between control and experimental groups within a scientific study. The control group establishes a standard for comparison by remaining under normal conditions, while the experimental group undergoes a specific change to test a hypothesis. Students are guided through a step-by-step strategy to identify these groups by locating the independent variable and comparing the resulting data. To reinforce these concepts, the source provides practical examples, such as testing the effects of caffeine or fertilizer. Finally, it highlights common mistakes, such as failing to recognize the control group as the "no change" baseline. Overall, the text serves as a functional guide for mastering experimental design and accurately interpreting scientific results.
