Final answer:
Field experiments, or randomized field trials, are conducted in real-world settings to test cause-and-effect hypotheses. They focus on observing human behavior and collecting accurate information without researcher intervention. However, establishing causation can be challenging due to the presence of multiple factors.
Step-by-step explanation:
Field experiments, also known as randomized field trials, aim to test cause-and-effect hypotheses by conducting experiments in real-world settings. These experiments focus on observing specific behaviors and phenomena in natural environments. Field experiments are often used to study human behavior and gather accurate information without intervention from researchers. However, they may struggle to establish a causal relationship between variables due to the presence of multiple factors in the natural environment.
