Final answer:
The purpose of an experiment is to test a hypothesis, collect data, and analyze results to establish a relationship between variables.
Step-by-step explanation:
The purpose of conducting an experiment is to test a hypothesis. An experiment is a process of systematic observations or measurements, often carried out under controlled conditions, designed to investigate the relationship between variables. Scientists use experiments to collect data and analyze results, drawing conclusions about whether the data supports or rejects the hypothesis. If experiments repeatedly support the hypothesis, it gains credibility as a dependable explanation of phenomena, whereas if it is rejected, a new hypothesis might be formed.
To carry out an experiment, the independent variable is manipulated, and the impact on the dependent variable is measured. Controlled experiments aim to isolate and assess the effect of a single variable at a time to establish cause-and-effect relationships. The careful design and repetition of experiments are crucial steps in validating or reshaping our understanding of the natural world.
