The methods of quantitative − quality standard of statistical connection between parameters of electrochemical system with the distributive values on an electrode are submitted. It is shown, that comparison of statistical units of estimation parameters can be carried out by the following principle: to a sign on a deviation from average values of sets; degrees of a deviation from average values of sets; to a sign and a degree of a deviation from near stand units, related to average value of such deviation in sets; in relative sizes of sites of an electrode with characteristic relations between statistical units. As a resultant of application of the proposed methods of a relations parameters estimation between the distributed parameters are developed. Application of similar statistical estimations allows to establish avai-lability of relations between the distributed parameters on an electrode, inaccessible other methods.
