Field experiments are a type of research method where researchers manipulate variables in real-world settings to observe the effects on participants. Unlike laboratory experiments, field experiments take place in natural environments, allowing for more authentic data collection and insights into human behavior. These experiments are commonly used in various fields, including psychology, sociology, and economics. By conducting field experiments, researchers can test hypotheses and evaluate interventions in a way that reflects real-life conditions, making their findings more applicable and relevant to everyday situations.
