Final answer:
Good science is marked by experiments that produce reliable data to convince experts of its credibility, and it involves transparent, repeatable processes that allow for the verification of results and falsifiability of hypotheses.
Step-by-step explanation:
A mark of good science is that it is backed up by experiments that have generated enough data to convince other experts of its legitimacy. In the scientific community, legitimacy comes from transparent and repeatable experimentation that yields data which can be examined by peers. This includes allowing others to replicate experiments to verify results and checking equations for errors. Furthermore, a scientific hypothesis must be one that can be tested and potentially falsified through careful experimentation and observation.
Experiments must be conducted properly, providing results that either support or contradict the predictions of a hypothesis. Repeated experiments that yield consistent results strengthen the likelihood of a hypothesis being a useful description of nature, although no number of experiments can absolutely prove a hypothesis to be correct. This hypothesis testing through experimentation is a cornerstone of scientific research and falsifiability is a key principle, ensuring that the information produced is reliable.
