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 important appointment. Understanding the nature of errors helps individuals learn and improve their decision-making skills. 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, on the other hand, occur unpredictably and can be caused by external factors. Recognizing these types can aid in minimizing mistakes in various fields.
