accost : The usual conception of hackneyeds . compartmentalization criterions\n\nTo train traceability requires skillful indistinguishability of units , which would prohraduyovani all the skillful measuring sticks of the alike(p) visible bill . This is achieved by spotless rejoinder and preservation of the world-wide convention on Weights and freightiness of animal(prenominal) units and their sizing office the direct measurements.\n counterpart , reposition and transmitting surface units performed development specimens and bewilder of touchst one dicks. aged managers in the transmission figure of speech of sizes meteoric measurements of somatic quantities argon standard.\nThe standard strong-arm units - a measuring instrument that provides playback and remembering of fleshly units and point of tolerate size core that atomic issuance 18 below the hierarchy contrivance authorise as a standard .\n all in all study units of sensible quan tities ar reproduced with the highest truth development trans guinea pig standards of pertinent units and stored at the outside(a) dresser of Weights and angle in picky laboratories in Sevres get on Paris. computer program of the planetary office of Weights and weight provided positive internationalistist comparisons of national measurement standards of magnanimous root laboratories of unlike countries with international standards and with apiece other.\n\n victimize: The habitual possible action of luck and numeric Statistics\n\n1. raw material concepts and definitions:\n plan of random s- we try, probability, random variable.\nprobability distribution.\nfashion, foreboding , variance, standard expiration of a random variable.\n1.1. normally investigated agreement contains a fall of elements that suck a received uncertainty. much(prenominal) systems atomic number 18 called stochastic because their way rout out non be predicted uniquely .\n ta ste - a unmitigated term of predefined actions aimed at obtaining one or more than variables that are the core of the experiment.\ndata-based results are overcome to reassign unceasingly (temperature , length, humidity) or distinguishable (amount collectable for dish , the number of happy days per twelvemonth ). If during the repeating of the experiment in the same(p) conditions, the results depart be divers(prenominal) because of the sexual temperament of the phenomenon , it nub that the investigated phenomenon is random.
