määrällisistä

Määrällisistä is the elative plural form of the Finnish adjective määrällinen, meaning "quantitative" or "numerical." In Finnish, adjectives agree with their noun in number and case, so when the adjective applies to plural nouns in the elative case, it takes the ending -isistä: määrällisistä.

The elative case often expresses source, origin, or context such as "from" or "out of," but when used with nouns in academic language it can also mean "in terms of" or "concerning" the data.

In practice, määrällisistä is used to describe data or measurements that are quantitative rather than qualitative (which would use laadullisista). It frequently occurs in phrases such as määrällisistä arvoista ("from quantitative values"), määrällisistä tiedoista ("from quantitative data"), or määrällisistä mittauksista ("from quantitative measurements").

Etymology: formed from määrä ("amount, quantity") plus the adjectival suffix -llinen, with the elative plural suffix -isistä to agree with a plural noun in the elative. The form is confined to adjectival usage; it does not stand alone as a noun.

See also: määrällinen; laadullinen; kvantitatiivinen. This term is common in statistical and research-language in Finnish, helping distinguish data that are measured on a numeric scale from qualitative descriptions.
