The purpose of an experiment is to test a hypothesis or to explore a specific question through systematic investigation. Experiments are designed to establish cause-and-effect relationships by manipulating one or more independent variables while keeping other factors constant.
When researchers conduct an experiment, they aim to gather evidence that supports or refutes their initial hypothesis. This process helps in understanding phenomena and contributes to the body of scientific knowledge. Experiments allow for controlled conditions where variables can be isolated, enabling researchers to draw more precise conclusions about the effects of those variables.
Furthermore, experiments can also help in validating existing theories or discovering new principles. They often involve repetition and peer review to ensure that results are reliable and can be replicated by others in the scientific community. In essence, the core purpose of an experiment is to gain insights into how the world works through structured and evidence-based testing.
