Nominaalinen

Nominaalinen is a Finnish adjective meaning nominal. In everyday language it can describe something in name only or not substantive, but in technical contexts it denotes values, data, or categories that are not adjusted, ranked, or otherwise treated as real or substantive.

In economics and finance, nominaalinen refers to values stated in current monetary terms without adjusting for inflation. Nominal GDP, for example, measures the market value of goods and services at current prices, whereas real GDP is adjusted for changes in the price level. Similarly, nominal wages are stated in current money terms, not adjusted for inflation.

In statistics and data analysis, nominaalinen data (nominal data) are qualitative categories that lack intrinsic order. Examples include eye color, car brands, or country of origin. Analyses of nominal data rely on frequencies and proportions and do not support arithmetic operations or ranking beyond categorization. Nominal variables are distinguished from ordinal variables, which have a meaningful order, and from interval/ratio scales, which support a wider range of mathematical operations.

The exact meaning of nominaalinen can vary by discipline. Beyond technical contexts, it may appear in general discussion to indicate something is true "in name only" or not enacted in practice, though this non-technical sense is less common in professional literature.
