At formation of magnitude of sample it is necessary to reckon with a general totality absolute value, the probable error of the centre decreases in the attitude inversely proportional to square root from among taken unities; at augmentation of number of observation in 4, 9, 25 and time, reliability of effects increases only in 2, 3, 5 and time.

Except the number, as a takeoff sign it is possible to use any letters of the alphabet. The essence of the yielded system of takeoff is grounded on the law of major numbers. However, that the law of major numbers could show the influence, takeoff should be effected in major enough terrain clearance number. - the g at about in about about about would consist that the probed mass preliminarily breaks into separate bunches on any spotting its composition and a state to a sign, and from the formed bunches takeoff of unities subject to observation is effected mechanical by. This view of takeoff, at other requirements, is less trusty, as an establishment of bunches inseparably linked with from the explorer in statement of examination of a known lobe of subjectivity. But at the same time group takeoff is necessary in case of strong the probed mass. Definition of magnitude of takeoff, at build-up of sampling examination on the basis of mechanical takeoff and also provided that the yielded sampling examination was preceded by continuous examination of the same phenomenon, is possible for the following formula: To construct on - - a h / "'--) where an o-average quadratic error , r-chastost (the attitude of terrain clearance number of events of probed event - - an aggregate number sampling ^ IT -), N-number of a general totality and p-number of a sample.

In last attitude samples, being pluralities "mass", constructed on sufficient number of observation, and, under condition of the correct statement of technics of takeoff, pluralities, blanket plurality, allow to tolerate properties characterising them (summary performances, on Orzhentsky) on a general totality. For the same reasons, samples in some cases can be constructed with the desirable accuracy rate dictated by problems and the purposes of examinations, and, revertively, the-samples received under yielded requirements of examination, can be estimated from the point of view of an accuracy rate of a picture pitched by them. From a monographic method differs that at the heart of it the mass lays, and at a monographic method the mass is unattainable as a matter of fact the method. From stated obviously, that the technician of takeoff and its dimensions in statement have essential value. On the positioned practice, the technics of takeoff can be effected or is pure mechanically or a mean group. At m and and with about with about takeoff of unities which are subject to recording or a cutout from a lump of records of continuous observation, is effected to any purely casual sign, but thus to such sign which is not included in the program of sampling examination. Most often applied sign is the order number or the alphabet. In case of the former from the continuous list of objects of observation or from their lump (for example, the list of peasants-domohozjaev or from a lump of the blanket statistical maps compounded in ambulance stations) those from them which appear in the list under any positioned numbers are culled or are in a lump under any order number (for example, 5, 10, 15 and at 20 %-s' takeoff).

Losievskaja). The proximate mode distinguishes from a biographical method that at examination biographical not continuous volume at takeoff grows out casual, a consequence some kind of deviations from the continuous examination planned under the plan; at particulate character of data it is received as effect of the conceived planned carrying out of incomplete recording of unities of examination. This distinction as though technical, actually is rather essential, imposing an impress on received as a result of application biographical and particulate pluralities of observation. Unlike a biographical method, representative character of the pluralities created at. It is provided from the very beginning of examination by that takeoff of observation units is effected on the basis of accident in sense of the law of probability; this circumstance, in turn, result ins to that the events meeting in the probed mass in number, get more chances to get to a sample, and the events meeting in it are more rare, will have smaller number of chances to be a part of the termed plurality. Sampling plurality-it reduced, in known, in advance positioned, a number of times, a picture whole (Miniaturbild), particulate plurality at a biographical method-it the unknown person on the dimensions and accuracy of transmission a copy of the probed phenomenon. A direct consequence of the specified various content of particulate pluralities at both viewed methods is distinction in possibility of an assessment and 819 the SAMPLING METHOD 820 them.

Reached from continuous a recouple of observation units accuracy of effects would differ in practical (but not in theoretical) the attitude from accuracy of the effects received at particulate examination a little. Data collected as a result differ from data of continuous examination by that they do not yield representation about terrain clearance number of unities concluded in their blanket plurality; but at the correct statement of takeoff they yield, to a greater or lesser extent, sufficient data for judgement about interior of the studied mass and about its partition on the homogeneous components. The basic moments spotting and distinguishing it from two other methods of not continuous examination-biographical of a method and a method monographic, are the trace, two lines: Represents a method purposely and meaningly made not continuous, but, nevertheless, mass statistical a recouple of events of the probed phenomenon or takeoff from total number of the collected observation at continuous examination, and at it is filed or culled in advance or precisely positioned part of events on special, also in advance spotted, to a mean and consistently made plan.

The essence consists that from a lump of events of the studied phenomenon is culled and major or their smaller part is filed. Such statement of examination gets essential value in following events of practice of statistical examination: first, when the interesting phenomenon by the nature cannot be studied by continuous calculus (as, for example, at examination of white and red pellets in blood, at studying of any objects vegetable and fauna; secondly, when this last cannot be applied behind a deficiency at the explorer of forces, resorts and time; Thirdly, when, though there is a possibility to supply examination on the basis of continuous calculus, but at the same time is obvious, that such statement would be deprived practical sense, to.
