Ponovljivost, reproducibilnost i utjecaj vizualnih stimulansa na vrednovanje opipa tkanina kroz dulje vrijeme
A lot of work and a big effort have been devoted to the area of understanding of sensory analysis of subjective hand evaluation and its objective prediction. So that the proposed models of objective evaluation can have validity for a longer time, the repeatability and reproducibility of total hand are necessary. In this paper the reproducibility, repeatability and influence of visual stimuli on the hand evaluation are verified by means of linear regression and using Spearman's rank correlation coefficient. Eleven degrees ordinal scale was applied and a sample rating median was analyzed. Three groups of respondents evaluated total hand during approximately one decade. The results indicate the possibility to reach repeatability and reproducibility of hand evaluation during long time period. Influence of visual stimuli was not proved clearly.
