An error, often referred to as a mistake, is an action or decision that deviates from what is correct or intended. Errors can occur in various contexts, such as in mathematics, where a miscalculation leads to an incorrect answer, or in daily life, where a person might forget an appointment. Understanding the nature of errors is essential for learning and improvement. Errors can be classified into different types, including human errors, systematic errors, and random errors. Human errors are often due to oversight or lack of knowledge, while systematic errors arise from consistent flaws in a process. Random errors are unpredictable and can occur due to unforeseen circumstances. Recognizing and analyzing errors helps individuals and organizations enhance their performance.
