Final answer:
Scientists use peer review, replication by other researchers, and statistical analysis of data to verify the results of an experiment, ensuring accuracy and credibility in scientific research.
Step-by-step explanation:
Scientists verify the results of an experiment through several methods to ensure accuracy and credibility. These include peer review by other scientists, which acts as a quality control measure to weed out poorly executed studies or improve well-designed ones; replication of the experiment by independent researchers to confirm reliability and consistency with other findings; and statistical analysis of the data to draw logical conclusions from the experimental results. These methodologies are crucial for maintaining the integrity and advancement of scientific knowledge.
