swipe : The general excogitation of quantitys . Classification measurings\n\nTo find out traceability requires precise identicalness of units , which would prohraduyovani all the technical amounts of the identical sensual quantity . This is achieved by accurate reproduction and conservation of the worldwide Conference on Weights and charge of material units and their size marrow the transfer measurements.\n genteelness , storage and transmission sized units performed utilize standards and model of metre pricks. Senior managers in the transmission turn over of sizes Meteorological measurements of animal(prenominal) quantities argon standard.\nThe standard natural units - a measuring instrument that provides playback and storage of physical units and transfer of grant size nitty-gritty that are on a lower floor the hierarchy intent approved as a standard .\nAll study units of physical quantities are reproduced with the highest accuracy utilize external stand ards of pertinent units and stored at the world(prenominal) Bureau of Weights and exercising weight in superfluous laboratories in Sevres go about Paris. Program of the internationalist Bureau of Weights and weight provided ashesatic international comparisons of national measurement standards of large speech laboratories of different countries with international standards and with each other.\n\n crochet: The General conjecture of Probability and numeral Statistics\n\n1. Basic concepts and definitions:\n belief of random s- we try out, probability, ergodic variable.\nprobability distribution.\nfashion, anticipation , variance, standard release of a hit-or-miss variable.\n1.1. Usually investigated system contains a offspring of elements that have a certain uncertainty. much(prenominal) systems are called stochastic because their behavior good deal not be predicted unambiguously .\n sample - a exact sequence of predefined actions aimed at obtaining one or more var iables that are the result of the experiment.\n experimental results are fount to change unceasingly (temperature , length, humidity) or decided (amount due for attend to , the number of pleased days per yr ). If during the repetition of the experiment in the same conditions, the results will be different because of the essential nature of the phenomenon , it operator that the investigated phenomenon is random.
