Quality Evaluation by Numerical and Subjective Methods, with Application to Dried Veneer
Walter G. Kauman, J. W. Gottstein, D. Lantican · Biometrics · 1956
Very different schemes have often been proposed for the evaluation of perceptual entities. Advocates of physical measurement, either by instruments or by unambiguously defined scoring systems, claim that any method of subjective evaluation will suffer from variability between and within observers, and from difficulties in training observers other than by personal tuition. Those advocating subjective evaluation schemes retort that for many of the quantities in question, physical measurement would be so involved as to be impracticable, and that the results, though reproducible, would often be meaningless for the intended purpose. If a simple, straightforward method of physical measurement is
