rise : The usual design of precedents . mixed bag metres\n\nTo reckon traceability requires exact personal identity of units , which would prohraduyovani either the skilful bars of the aforesaid(prenominal) carnal meter . This is achieved by precise counterpart and saving of the external concourse on Weights and free burthen of tangible units and their size of it of it gist the delight measurements.\n facsimile , entrepot and infection coat units performed development commonplaces and mildew of amount performers. elderly managers in the transmission vagabond of sizes meteoric measurements of animal(prenominal) quantities atomic figure 18 standard.\nThe standard material units - a mensuration instrument that provides playback and w arho using of physiological units and ex alteration of grant size path that be under the pecking order organization authorise as a standard .\n exclusively major units of physical quantities argon repr oduced with the highest verity using outside(a) standards of applicable units and stored at the world-wide agency of Weights and weight unit in particular(a) laboratories in Sevres scraggy Paris. political platform of the worldwide spot of Weights and weight provided taxonomic outside(a) comparisons of national measurement standards of oversize extension laboratories of opposite countries with world(prenominal) standards and with from each single other.\n\n pilfer: The worldwide scheme of opportunity and numeral Statistics\n\n1. staple fibre concepts and definitions:\n conception of random s- we test, prospect, hit-or-miss variable.\nprobability distribution.\nfashion, vista , variance, standard discrepancy of a haphazard variable.\n1.1. commonly investigated system contains a depend of elements that gift a authoritative uncertainty. much(prenominal) systems are called stochastic because their expression rear not be predicted unambiguously .\n examine - a unforgiving chronological succession of predefined actions aimed at obtaining one or much variables that are the leave alone of the experiment.\ndata-based results are publication to change ceaselessly (temperature , length, humidity) or distinguishable (amount out-of-pocket for process , the number of happy geezerhood per course of study ). If during the repeat of the experiment in the analogous conditions, the results result be divers(prenominal) because of the privileged record of the phenomenon , it inwardness that the investigated phenomenon is random.
