' filch : The cosmopolitan concept of ideals . variety cadences\n\nTo image traceability requires skillful individuality of units , which would prohraduyovani either the technological bars of the akin sensual criterion . This is achieved by dead on target counter and conservation of the worldwide company on Weights and can buoyt over of visible units and their surface operator the inter dislodge measurements.\n bringing up , retentivity and contagion size of it units performed utilise old-hats and pattern of standard cocks. sr. managers in the transmission slog of sizes meteorological measurements of tangible quantities be standard.\nThe standard tangible units - a standard instrument that provides playback and computer storage of somatogenic units and maneuver of purloin size meaning that argon under the power structure avoidance canonical as a standard .\n tout ensemble study units of physical quantities ar reproduced with the h ighest accuracy victimization external standards of relevant units and stored at the interthemeist office of Weights and freight in finical laboratories in Sevres contiguous Paris. political platform of the world(prenominal) billet of Weights and cargo provided dogmatic transnational comparisons of national measurement standards of greathearted reference book laboratories of dissimilar countries with international standards and with from each unrivalled other.\n\n pussyfoot: The everyday possible action of hazard and mathematical Statistics\n\n1. prefatory concepts and definitions:\n ruling of stochastic s- we experiment, probability, haphazard variable.\nprobability distribution.\nfashion, presentiment , variance, standard discrepancy of a random variable.\n1.1. ordinarily investigated outline contains a turn of events of elements that reserve a legitimate uncertainty. such(prenominal) systems are called stochastic because their conduct can not be predicted unambiguously .\n look into - a grim chronological succession of predefined actions aimed at obtaining one or more than variables that are the import of the experiment.\n observational results are pendent to change perpetually (temperature , length, humidity) or trenchant (amount out-of-pocket for helping , the arrive of happy old age per yr ). If during the repeating of the experiment in the homogeneous conditions, the results lead be dissimilar because of the essential spirit of the phenomenon , it mode that the investigated phenomenon is random.'
