asteikkopohjaisia

Asteikkopohjaisia is a Finnish adjective describing something that is based on a scale with discrete steps. It is commonly used to refer to instruments, questions, measurements, or evaluations that yield data organized on an ordered scale, such as rating or Likert-type scales. The term appears in academic and professional language across fields like psychology, education, sociology, market research, and quality assessment.

In practice, asteikkopohjaiset järjestelmät include examples such as kysymykset with answer options arranged from low to high (for example 1 to 5), arviot on a numerical or verbal scale, or rubrics that assign levels of performance. The data produced are typically ordinal, meaning the order of categories is meaningful, though the intervals between categories are not necessarily equal. Despite this, many researchers treat common Likert-type scales as having approximate interval properties for analysis.

Common usage highlights include phrases like asteikkopohjaiset kysymykset, asteikkopohjaiset mittarit, or asteikkopohjaiset arviot. The concept contrasts with nominal or dichotomous measurements, which do not imply ordered categories. When designing asteikkopohjaisia instruments, researchers consider issues such as the number of scale steps, label wording, and whether the step distances are perceived as equal by respondents.

Etymology: asteikko means scale and pohja indicates base or foundation, together signaling measures built on a graduated scale. Related terms include Likert-asteikko, semanttinen differenssi, and muut mittaristot.
