An error (from the Latin error, meaning "wandering") is an action which is inaccurate or incorrect. In some usages, an error is synonymous with a mistake (for instance, a cook who misses a step from a recipe might describe it as either an error or a mistake), though in technical contexts the two are often distinguished. For instance, in statistics "error" refers to the difference between the value which has been computed and the correct value.
