How is a Wikipedia error corrected?

To correct an error on Wikipedia, a user can edit the relevant article directly, provided they have an account or are willing to edit anonymously. They should ensure that their corrections are based on reliable sources and follow Wikipedia's guidelines for citations. After making the changes, the edit can be summarized, and the user can save the modifications. Other editors may review the changes, and if necessary, further discussions can occur on the article's talk page.
