Are ordinal rating scales better than percent ratings? A statistical and “psychological” view

2007-05-01

Abstract excerpt

Disease incidence and severity are often assessed by either an ordinal rating scale, e.g., with scores from 1 to 9, or a percentage rating scale. This paper compares three different rating scales regarding accuracy, precision, and time needed for scoring. Pictograms of mildew diseased cereal leaves were generated following a right skewed beta-distribution. Persons with different rating experience were asked to rat...
