laadullisilla

Laadullisilla is a Finnish grammatical form used to describe qualitative attributes or approaches when referring to plural nouns in the adessive case. It is the plural plural-adessive form of the adjective laadullinen, which means something like “qualitative” or “related to quality.” In practice, laadullisilla appears in phrases that discuss methods, data, or findings in terms of quality rather than quantity.

Etymology and morphology: laadullinen is formed from the noun laatu (quality) plus the suffix -llinen, meaning “having the quality of.” The adessive plural ending -illa attaches to a compatible plural noun, yielding forms such as laadullisilla tutkimuksilla (with qualitative studies) or laadullisilla menetelmillä (with qualitative methods). This construction is common in academic and research texts.

Usage in research and analysis: Laadullisilla is typically used to contrast qualitative approaches with määrällisillä (quantitative) approaches. It describes characteristics, data collection, or analysis that emphasize meaning, interpretation, and context rather than numerical measurement. Examples include: Laadullisilla tutkimuksilla pyritään ymmärtämään ilmiön syvät piirteet, ja ne voivat tarjota kontekstuaalista tietoa. (Qualitative studies aim to understand the deep features of a phenomenon and can provide contextual information.)

See also: Laadullinen tutkimus, qualitative research; määrällinen tutkimus, quantitative research. The term appears most often in social sciences, education, and market research when distinguishing data collection and analysis strategies.

Overall, laadullisilla functions as a grammatical tool to articulate qualitative attributes in plural, guiding readers to interpret findings in terms of quality and meaning rather than count.
