erros

Erros is the Portuguese term for errors and refers to deviations from accuracy, truth, or a desired outcome. In everyday use it covers mistakes, faults, or misjudgments across disciplines. The concept is central to measurement, computation, language, and reasoning.

In measurement and science, errors are differences between observed values and the true value. They are often categorized as systematic (bias) errors, which skew results in a consistent direction, and random (unsystematic) errors, which vary unpredictably. Descriptions of errors include magnitude, confidence intervals, and error margins. Methods to reduce errors include calibration, replication, and robust experimental design.

In statistics and data processing, errors can be sampling errors or non-sampling errors; measurement errors occur when data collection instruments introduce inaccuracies. Error analysis aims to identify sources and quantify impact, guiding improvements in data collection and interpretation.

In computing, errors manifest as bugs or exceptions. Programs use error handling, input validation, and fail-safe designs to manage them. Logging, debugging, and testing help minimize the risk of errors affecting users and system reliability.

In language and learning, a learner's errors reveal knowledge gaps; error analysis distinguishes errors from slips of the tongue or careless mistakes. In philosophy, error theory questions the existence of moral facts and contends that all moral claims are false, illustrating how the concept of error can extend to normative discourse.
