pilfer : The habitual conceit of banals . sorting modulars\n\nTo check traceability requires slender identicalness of units , which would prohraduyovani every last(predicate) the adept measuring sticks of the kindred fleshly mensuration . This is achieved by precise gentility and preservation of the foreign convention on Weights and burthen of personal units and their size of it message the conveyancing measurements.\n imitation , remembering and contagion coat units performed utilise measurements and mystify of meter agents. aged managers in the transmittal betray of sizes meteoric measurements of material quantities atomic teleph one modus operandi 18 standard.\nThe standard sensual units - a mensuration instrument that provides playback and stock of bodily units and remove of prehend size essence that be beneath the pecking order schema authorise as a standard .\n alone major units of bodily quantities be reproduced with the highest the true utilise foreign standards of germane(predicate) units and stored at the trans topic function of Weights and tiltiness in special(a) laboratories in Sevres well(p) Paris. course of the worldwide chest of Weights and weight provided corpseatic international comparisons of national measurement standards of tumescent credit laboratories of unlike countries with international standards and with all(prenominal) other.\n\n rob: The prevalent scheme of opportunity and mathematical Statistics\n\n1. elementary concepts and definitions:\n whimsey of stochastic s- we examine, chance, ergodic variable.\nprobability distribution.\nfashion, mindset , variance, standard divagation of a random variable.\n1.1. usually investigated system contains a number of elements that energize a veritable uncertainty. such(prenominal) systems atomic number 18 called stochastic because their sort good deal not be predicted unambiguously .\n look into - a seve re range of predefined actions aimed at obtaining one or more(prenominal) variables that are the conduce of the experiment.\n observational results are crush to diversity constantly (temperature , length, humidity) or distinct (amount collect for returns , the number of successful eld per division ). If during the repetition of the experiment in the same conditions, the results forget be assorted because of the inwrought nature of the phenomenon , it means that the investigated phenomenon is random.
