Testing the Sturdiness of Clinical Criteria with Different Methods of Simple Statistical Analysis,

Abstract

A set of 96 samples composed of 6 subsets was evaluated by photographic and direct observation. Using a set of subjective criteria for excellence, the samples were rated by 3 different evaluators in both ordinal and categorical scales. The various data sets resulting were subjected to analysis by Krashal-Wallis and STP procedures (for the ordinal data) and by Ridit analysis (for the categorical data). It was found that the ordinal data produced consistent results both by photographic and direct evaluation. The Ridit analysis creates an informative index of excellence which allows a quality level value to be given to an irregular distribution. It is a practical method for producing data conducive to graphic display. Certain pitfalls in Ridit analysis make more complex analysis problematic. (Author)
