deviáció

Deviáció is a term used in statistics and other fields to describe a departure from a standard, norm, or expected value. It quantifies how much a particular data point or observation differs from a reference point, which can be a mean, median, or other benchmark. The concept of deviation is fundamental to understanding the spread and variability within a dataset.

A positive deviation indicates that a value is above the reference point, while a negative deviation signifies it is below. The magnitude of the deviation is important; a large deviation suggests a significant difference from the norm, whereas a small deviation implies the value is close to the reference. Common measures that utilize deviation include variance and standard deviation, which are statistical tools used to assess the dispersion of data points around the mean.

In fields beyond statistics, deviáció can refer to any instance of moving away from a prescribed course, rule, or behavior. This could encompass deviations in physical trajectories, deviations from ethical guidelines, or deviations in planned processes. The context in which deviáció is used dictates the specific meaning and method of quantification. Understanding deviáció is crucial for identifying anomalies, assessing risks, and making informed decisions based on observed data or behavior.
