Inline graphicCron – Cronbach’s coefficient of reliability measured with the classical measuring method on original (Cron.) and standardized (SB) results on the assumption that all particles equally determine the subject of measurement; Inline graphicKC – Kaiser-Caffrey’s coefficient of reliability measured with the classical measuring method on standardized values of entities on a linear combination of test particles; Inline graphicGuttman-Nicewander’s coefficient of reliability measured with the Guttman’s measurement model by transforming the results of entities in particles into universal (Harris’) metrics (Harris, 1962); h1 – homogeneity of the test particles based on the number of principal components with positive coefficients of reliability Inline graphic1 – first typical value of the correlation matrix among the experts; V% – percentage of common variance of the experts’ opinions; msa – Kaiser-Rice’s coefficient of the experts’ representation determined on the basis of an evaluation of the size of the error expressed as a ratio between the sum of the correlation matrix squares of the anti-image variables and the sum of the correlation matrix squares
