experiments

Experiments are structured investigations designed to test ideas or hypotheses. They involve creating a controlled environment where variables—factors that can change—are carefully manipulated to observe their effects. By comparing outcomes under different conditions, researchers can determine if their ideas are correct or need adjustment. For example, testing a new medicine involves giving it to some people and not to others, then observing differences in health outcomes. Experiments help us understand cause-and-effect relationships, enabling scientific progress across fields like medicine, physics, and social sciences. They rely on careful planning, accurate measurements, and objective analysis.
