Having calculated the coefficients of correlation between R sub m (dependent variable) and each of the chemical constituents in three analysed series, specification of correlation matrixes separately for each series, as well as coefficients of partial and multiple correlations, a multiple regression equation was computed showing the dependence of R sub m on the chemical composition. The significance of the obtained coefficients of regression has been checked. For each series diagrams have been made showing the changes of R sub m in dependence on the content of C in steel, which varies according to the analyzed steel type from 0.20% to 0.42% C. Equations, diagram, curves, and tables show data.
