RELATIVE ERROR Meaning and
Definition
-
Relative error is a mathematical quantity used to measure the accuracy or precision of a measurement or approximation, by comparing it to the true or accepted value. It is expressed as a ratio or a percentage, and reflects the deviation between the measured value and the actual value being measured.
In physics, relative error is defined as the absolute value of the difference between the measured value and the true value, divided by the true value. Mathematically, it can be represented as:
Relative Error = |Measured Value - True Value| / True Value
This formula allows the relative error to be independent of the units of measurement, making it a useful tool for comparing the precision of different measurements or experiments.
The relative error can also be expressed as a percentage by multiplying the ratio by 100. This allows the comparison to be easily understood in a more familiar format.
Relative error is commonly used in scientific experiments, engineering calculations, and statistical data analysis. It provides a quantitative measure of the accuracy of a measurement or approximation, helping to assess the reliability of the data or estimation. The smaller the relative error, the closer the measured value is to the true value, indicating higher accuracy or precision. Conversely, a larger relative error indicates a more significant deviation from the true value, suggesting lower accuracy or precision.

Etymology of RELATIVE ERROR
The word "relative" comes from the Latin word "relativus", which means "related". It is formed from the combination of the word "re-" meaning "back" or "again" and "latus" meaning "carried" or "borne". The term "error" comes from the Latin word "error", which means "to wander" or "to stray". Its origin can be traced back to the combination of the prefix "ex-" meaning "out of" and the root "-currere", meaning "to run".
Therefore, the etymology of the term "relative error" suggests that it refers to the error or discrepancy between values in relation to each other, rather than an absolute or independent error.
