Measure that is defined as a function of two or more values of base measures. [ ISO/IEC 99, ISO/IEC 15939, ISO/IEC 25000 ]
- A derived measure is a measure that is defined as a function of two or more values of base measures. Derived measures capture information about more than one attribute or the same attribute from multiple entities. Simple transformations of base measures (for example, taking the square root of a base measure) do not add information, thus do not produce derived measures. Normalisation of data often involves converting base measures into derived measures that can be used to compare different entities. [ ISO/IEC 15939 ]
- A transformation of a base measure using a mathematical function can also be considered as a derived. [ ISO/IEC 25000 ]
