Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
The final score lies along a pre-set scale of values, and scorers try to apply the scale consistently. The final score for the piece of writing is derived from two or more independent ratings. Holistic scoring is often contrasted with analytic scoring. [5] [6] [7]
A scoring rubric typically includes dimensions or "criteria" on which performance is rated, definitions and examples illustrating measured attributes, and a rating scale for each dimension. Joan Herman, Aschbacher, and Winters identify these elements in scoring rubrics: [3] Traits or dimensions serving as the basis for judging the student response
