If an error is entered, what is the proper way to correct it?

When correcting an error, drawing a line through the mistake and noting the details is the proper approach because it maintains a clear record of what happened. This method provides transparency, allowing anyone reviewing the document to understand that an error was made and how it was corrected. It preserves the integrity of the document while providing an opportunity to explain the nature of the error and the correction made. This practice is especially important in formal documentation or records where accuracy and accountability are critical. By documenting the error, you also create a reference that can be helpful for future audits or reviews.

In contrast, erasing the error completely can create confusion or the appearance that the mistake was never made, which could lead to accountability issues down the line. Leaving the error as is may also lead to misunderstandings, especially if the context is unclear. Notifying a supervisor might be necessary in certain contexts, but it does not directly address how to correct the error itself; thus it is not the most comprehensive solution for rectifying a mistake in documentation.
