Error analysis is a process used to identify and analyze mistakes or errors in order to improve performance, correct problems, and prevent future occurrences. It involves examining specific events or situations where errors occurred, determining why they happened, and finding ways to address them so that similar issues do not happen again. Error analysis can be applied in various fields such as science, technology, medicine, education, business, and many others. The goal is to identify the root cause of the error, whether it's a systemic issue or an individual mistake, and take steps to prevent future errors from happening.
