Common methods of conducting a probability sample of the household population in the United States are Area Probability Sampling, Random Digit Dial telephone sampling, and more recently Address-Based Sampling.

* Sampling methods for censuses and surveys ( 1949 )

Sampling theory provides methods for calculating the probability that the poll results differ from reality by more than a certain amount, simply due to chance ; for instance, that the poll reports 47 % for Kerry but his support is actually as high as 50 %, or is really as low as 44 %.

Sampling of water for physical or chemical testing can be done by several methods, depending on the accuracy needed and the characteristics of the contaminant.

** Sampling, measurement and evaluation practices ( instrumentation, sampling protocols, methods or techniques, analytical chemistry );

Sampling may refer to:

Sampling error always refers to the recognized limitations of any supposedly representative sample population in reflecting the larger totality, and the error refers only to the discrepancy that may result from judging the whole on the basis of a much smaller number.

Sampling risk is the risk the auditor ’ s conclusion may be different from the conclusion that would be not be reached

# Modern surfaces: Sampling modern surfaces for use with archeobotanical data may be used to create a reference collection, if the taxa being sampled are known.

This sufficient condition can be weakened, as discussed at Sampling of non-baseband signals below.

* Sampling ( audit ), application of audit procedures to less than 100 % of population to be audited

Sampling the waveform at higher frequencies and allowing for a greater number of bits per sample allows noise and distortion to be reduced further.

Sampling the oxygen concentration in the pulmonary artery is a highly invasive procedure, but fortunately another similar gas can be used instead that obviates this need.

Sampling can be done for functions varying in space, time, or any other dimension, and similar results are obtained in two or more dimensions.

* Sampling: Sampling with a kernel can be considered a one-form, where the one-form is the kernel shifted to the appropriate location.

Sampling bias is systematic error due to a non-random sample of a population, causing some members of the population to be less likely to be included than others, resulting in a biased sample, defined as a statistical sample of a population ( or non-human factors ) in which all participants are not equally balanced or objectively represented.

Sampling of plants or animals that do not move much ( such as snails ), can be done using a sampling square called a quadrat.

Sampling of cumulus cells can be performed in addition to a sampling of polar bodies or cells from the embryo.

Sampling areas were stratified by environmental variables likely to be conducive to pathogen growth and by proximity to possible points of inoculum introduction such as nurseries.

* The Sampling Effect The sampling effect of diversity can be thought of as having a greater chance of including a species of greatest inherent productivity in a plot that is more diverse.

Sampling frequencies of 96 kHz or 192 kHz can be used on some newer equipment, with the higher value equating to 6. 144 megabit per second for two channels at 16-bit per sample value.

Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here.

Sampling was deemed to not be a fair use, because the " samples " were in fact permanent and complete copies of the desired media.

Sampling error can be measured and quoted in many different ways, but in practice the reported error itself is almost always an estimate of the real error rather than an absolute measure of the error ( which would usually require analyzing the entire population ).

Sampling always refers to a procedure of gathering data from a small aggregation of individuals that is purportedly representative of a larger grouping which must in principle be capable of being measured as a totality.

Sampling error can be contrasted with non-sampling error.

Sampling the integral for a point can be done by solely gathering from the surface, or by solely shooting rays from light sources.

What sampling method to use ?- examples: Probability Sampling :- ( cluster sampling, stratified sampling, simple random sampling, multistage sampling, systematic sampling ) & Nonprobability sampling :- ( Convenience Sampling, Judgement Sampling, Purposive Sampling, Quota Sampling, Snowball Sampling, etc.

Sampling error also refers more broadly to this phenomenon of random sampling variation.

** Systematic Sampling – involves selecting sampling units using a fixed interval between selections with the first interval having a random start.

; Sampling rate: Speex is mainly designed for three different sampling rates: 8 kHz ( the same sampling rate to transmit telephone calls ), 16 kHz, and 32 kHz.

See Sampling ( signal processing ) and Nyquist rate ( relative to sampling ).

* Photonic Sampling, using the high accuracy of lasers over electronic clocks to decrease the sampling error in electronic ADCs

* TRSL – Template Range Sampling Library is a free-software and open-source C ++ library that implements systematic sampling behind an ( STL-like ) iterator interface.

The World Values Survey uses the sample survey as its mode of data collection, a systematic and standardized approach to collect information through interviewing representative national samples of individuals. The basic stages of a sample survey are Questionnaire design ; Sampling ; Data collection and Analysis.

the coefficients are equivalent to samples of S < sub > 1 / T </ sub >( ƒ ) at discrete intervals of 1 / P = 1 / NT: ( see DTFT / Sampling the DTFT )

* Sampling ( medicine ), gathering of matter from the body to aid in the process of a medical diagnosis and / or evaluation of an indication for treatment, further medical tests or other procedures.

* Sampling frequency 8 kHz / 16-bit ( 240 samples for 30 ms frames )

* A Sampling of Chinglish NY Times 2010 / 05 / 03

In most countries the population size and / or degree of urbanization of these Primary Sampling Units are taken into account.

Sampling for biological testing involves collection of plants and / or animals from the surface water body.

Sampling at 13. 5 MHz was used as it is a common multiple of NTSC / PAL line rate ( 6x 2. 5 MHz ).

The journal is divided into the following sections: Morphology, Systematics, Evolution ; Sampling, Distribution, Dispersal ; Development, Life History ; Population and Community Ecology ; Behavior, Chemical Ecology ; Population Biology / Genetics ; Molecular Biology / Genomics ; Neurobiology, Physiology, Biochemistry ; Vector Control, Pest Management, Resistance, Repellents ; Arthropod / Host Interaction, immunity ; Vector / Pathogen / Host Interaction, Transmission ; Vector Borne Diseases, Surveillance, Prevention ; Direct Injury, Myiasis, Forensics ; Modeling / GIS, Risk Assessment, Economic Impact.

Later models included the K2000VP ( keyboard ), K2000VPR ( rack ), K2VX ( keyboard w / optional ROMs ), and K2VXS ( keyboard w / optional ROMs + Sampling ) which were based on the same hardware as the K2000 series but had the K2500 sound set loaded.
