Random sample.

A random sample is a sample whose members are chosen at random from a given population in such a way that the chance of obtaining any particular sample can be computed. the number of units in the sample is called the sample size, often denoted n. the numb

Random, английский
- A dismissive description of an uninteresting and unimportant person... can also be used to describe an odd or amusing situation example person a how was that party last night? person b ehh, it was okay...it was mostly a bunch of randoms. or, what the hell was that? that was so random!
- A случайный hole, pattern
- Случайный; случайно выбранный
- Случайный; произвольный; беспорядочный; нерегулярный
- Случайный, произвольный; произвольно выбранный; беспорядочный, хаотичный
- Attribute of a process that is entirely or largely governed by chance, e.g., a roulette wheel, dice, the brownian movement, but also the pattern on the screen of a television set receiving atmospheric noise only. perfect randomness rarely exists in nature and is difficult to simulate. in practice, randomness is confined by particular parameters, e.g., a roulette wheel is expected to be random only within a range of numbers, not regarding how long the wheel takes to pick one, and it may even deviate from the ideal of uniform probabilities (->probability), e.g., when the roulett wheel is biased. the simulation of randomness by computers utilizes so-called pseudo random generators whose behavior is nearly impossible to predict without knowledge of the starting number and its algorithm (->generative) • ~ of a transformation
Random, английский
An unknown person (stranger). example we met a few randoms at the party last night.

Random (adj), английский
Specifically, a reference to an arbitrary or unpredictable situation or event. the term is also given an extended, pejorative or semi-pejorative meaning, however, in which it is used in the sense of nonspecific, incoherent, poorly organized, loser, and so on.

Random access memory (ram), английский
Запоминающее устройство с произвольной выборкой. электронная схема, обычно называемая "память", хранящая цифровую информацию в течение времени, пока к ней приложено напряжение. емкость памяти измеряется в килобайтах. память представляет собой рабочее пространство компьютера.
Random access memory cache, английский
Cache memory that is used by the system to store and retrieve data from the ram. frequently accessed segments of data may be stored in the cache for quicker access compared with secondary storage devices such as disks.

Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.

Chance variation, chance error., английский
A random variable can be decomposed into a sum of its expected value and chance variation around its expected value. the expected value of the chance variation is zero; the standard error of the chance variation is the same as the standard error of the ra
Quota sample., английский
A quota sample is a sample picked to match the population with respect to some summary characteristics. it is not a random sample. for example, in an opinion poll, one might select a sample so that the proportions of various ethnicities in the sample matc
