The testing function is distributed according to ( X 2 ) rule with (s-1) (t-1), in which s stands for row numbers and t for column numbers in the table. After calculation, we decided on the numeral value of the testing function, which was observed by frequencies and its
comparison with the critical table number ( X 2 ) toward hypothesis
H0. Note that the aforementioned test was used for many society comparisons (many distributions) and was applied in comparing the
answers of different organizational classes or different work records.
b) Calculation of Cherperof dependency coefficient: If the relation between two X and Y variables is verified, Cherperof dependency
coefficient is used to determine the dependency intensity or degree.This coefficient varies from 1 to 0, in which case the dependency of
the two variables is more when it is closer to 1:
