What is a peer-reviewed research article and how does the peer review process ensure the quality and credibility of the information presented in such articles?

A peer-reviewed research article is a scholarly paper that has been evaluated by experts in the same field before publication. The peer review process ensures the quality and credibility of the information by having independent experts assess the article for accuracy, validity, and significance. This helps to identify and correct errors, improve clarity, and ensure that the research meets the standards of the scientific community before it is published.
