A laboratory experiment is a scientific study conducted in a controlled environment where researchers manipulate variables to understand their effects on a specific phenomenon. Laboratory experiments typically involve a researcher or a team of researchers conducting controlled experiments in a lab setting, using various equipment, instruments, and materials to collect data and analyze results. This type of research method is commonly used in fields such as psychology, biology, chemistry, and physics to test hypotheses, establish causal relationships, and investigate scientific questions. The controlled nature of the lab environment allows for precise measurements and the ability to isolate and control variables, making it an effective approach for exploring cause-and-effect relationships in a systematic and rigorous manner.
