intervallocijfer

Intervallocijfer is a term used in some Dutch mathematical and statistical contexts to denote a single numerical value that represents a quantity known to lie within a specified interval of uncertainty. The word blends interval (interval) and cijfer (digit or figure). It is not a standard term in formal mathematical literature, and its precise meaning can vary between authors or educational materials.

In practice, an intervallocijfer serves as a representative value within an interval, such as a confidence interval or a measurement tolerance. It may be chosen as the interval midpoint, as the lower or upper bound, or as another policy-driven value depending on reporting needs or risk considerations. The concept is therefore more about a practical descriptor for a value within uncertainty bounds than about a fixed formal definition.

The term often appears in instructional contexts or data reporting where a single figure is preferred for readability, while the accompanying interval expresses the uncertainty. It is closely related to, but distinct from, standard notions such as a point estimate, an interval estimate, or a confidence interval. In formal practice, terms like midpoint, bounds, or interval estimates are more common, but intervallocijfer may be encountered as a descriptive label in some Dutch-language materials.

Because intervallocijfer is not widely standardized, its interpretation should be clarified in context. When encountered, readers are advised to check the specific source for how the term is defined and applied. See also interval estimation, confidence interval, point estimate, and interval arithmetic.
