Basisverhouding

Basisverhouding is a term used to denote a ratio that compares a quantity to a defined base or baseline. It expresses how large or small a value is relative to the chosen reference, and it often results in a dimensionless number when the base is consistently defined. The concept is used to express proportional change, benchmarking, and normalization across different contexts.

In practice, basisverhouding appears in fields such as accounting and budgeting, statistics, engineering, and policy analysis. It is used to describe how actual figures relate to a baseline—for example, how actual spending compares with a budget, how observed data compare with a reference value, or how a measurement aligns with a calibration standard. Depending on the domain, the base value and the interpretation of the ratio can vary.

Calculation is straightforward: basisverhouding = measured value / baseline. If the baseline is 100 units and the measured value is 120 units, the basisverhouding is 1.2, or 120% when expressed as a percentage. The precise interpretation (whether the ratio is a factor, a percentage, or an index) depends on the context and the chosen base.

Note that the meaning of basisverhouding can differ between domains, so explicit documentation of the selected baseline is important. See also ratio, normalization, and baseline.
