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 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 methods may be either ' random ' ( random sampling, systematic sampling, stratified sampling, cluster sampling ) or non-random / nonprobability ( convenience sampling, purposive sampling, snowball sampling ).

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

* Reject Inference for removing Sampling Bias.

# Sampling and analog-to-digital conversion ( ADC ) ( Sometimes before or instead of the above point, for example by means of undersampling ).

Sampling influences from electronica, rap, R & B and new age, Robyn received rave reviews, and gained the singer three Swedish Grammy Awards in 2006 for " Årets Album " ( Best Album ), " Årets Kompositör " ( Best Writer, alongside Klas Åhlund ) and " Årets Pop Kvinnlig " ( Best Pop Female ).

Sampling is the process of converting a signal ( for example, a function of continuous time or space ) into a numeric sequence ( a function of discrete time or space ).

Black's later chapter on " The Sampling Principle " does give Nyquist some of the credit for some relevant math:

* Sampling ( case studies ), selection of cases for single or multiple case studies

* 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 ( for testing or analysis ), taking a representative portion of a material or product to test ( e. g. by physical measurements, chemical analysis, microbiological examination ), typically for the purposes of identification, quality control, or regulatory assessment

; 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.

Sampling via deep trawling indicates that lanternfish account for as much as 65 % of all deep-sea fish biomass.

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

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

* ASTM E105 Standard Practice for Probability Sampling Of Materials

* ASTM E141 Standard Practice for Acceptance of Evidence Based on the Results of Probability Sampling

* ASTM E1994 Standard Practice for Use of Process Oriented AOQL and LTPD Sampling Plans

* ASTM E2234 Standard Practice for Sampling a Stream of Product by Attributes Indexed by AQL

Umbrella Sampling is used to move the system along the desired reaction coordinate by varying, for example, the forces, distances, and angles manipulated in the simulation.

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

Sampling surveys, on the other hand, have the goal of obtaining a representative sample of some population of sites or artifacts in order to make generalizations about that population.

Still, I was disgusted with myself for agreeing with Montero's methods.

Indeed, you wouldn't live long, for the females either drive the men they've seized from neighboring islands back to their boats after exploiting them for amatory purposes, or they destroy them by revolting but ingenious methods.

The Hetman had a strong liking for a story, any story which was to be had by means of much sleuthing or by roundabout methods.

The decision maker who acts for the community as a whole must decide whether the objectives pursued and the methods used are appropriate to public policy regarding cultural groups.

conduct, encourage, and promote fundamental scientific research and basic studies to develop the best and most economical processes and methods for converting saline water into water suitable for beneficial consumptive purposes ; ;

study methods for the recovery and marketing of commercially valuable byproducts resulting from the conversion of saline water ; ;

undertake economic studies and surveys to determine present and prospective costs of producing water for beneficial consumptive purposes in various parts of the United States by the leading saline water processes as compared with other standard methods.

The vast task of economic development urgently requires skilled people to do the work of the society -- to help teach in the schools, construct development projects, demonstrate modern methods of sanitation in the villages, and perform a hundred other tasks calling for training and advanced knowledge.

The need for interchange and understanding makes vital the full use of all methods of consultation.

By 1937 he had clarified his intentions to serve his people: `` I have striven for clarity and melodious idiom, but at the same time I have by no means attempted to restrict myself to the accepted methods of harmony and melody.

Not all the observers have used the same procedures or made the same assumptions about the lunar brightness distribution when reducing the data, and this, together with differences in the methods of calibrating the antennae and receivers, must account for much of the disagreement in the measured radio brightness temperatures.

Such an instrument is expected to be especially useful if it could be used to measure the elasticity of heavy pastes such as printing inks, paints, adhesives, molten plastics, and bread dough, for the elasticity is related to those various properties termed `` length '', `` shortness '', `` spinnability '', etc., which are usually judged by subjective methods at present.

Of several methods employed for tagging chlorine with radiochlorine, the exchange of inactive chlorine with tagged aluminum chloride at room temperature was found to be the most satisfactory.

Here we shall restrict discussion to those methods that appear sufficiently sensitive and precise for determining the concentration of TSH in blood.

Brown ( 1959 ) has reviewed generally the various methods of assaying TSH, and the reader is referred to her paper for further information on the subject.

Doubtless it was inevitable that differences of opinion should arise about the methods for applying these policies.

The foregoing have been methods of charting prices, but now let us look at some of the other indices that are customarily charted, and which are looked to for their forecasting abilities.

The quest for methods

The purpose set forth at the beginning of this book was first to introduce the reader to a general background knowledge of the various types and capabilities of the forecasting methods already in use, so that he might then be in a position to evaluate for himself the validity of the rather astonishing empirical correlation that is to follow, and to appraise the forecast that its interpretation suggests for the future of farm prices over the years immediately ahead.

There were two methods that could have been used for conducting the study within the resources available: ( 1 ) interviews in depth with a few selected companies, and ( 2 ) the more limited interrogation of a large number of companies by means of a mail questionnaire.

Teaching methods, learning materials, and promotion policies may inhibit learning and lead to maladjustments for some children.

The anaerobic conditions in the existing oxidation pond necessitated examination of other methods for supplying additional oxygen than by sodium nitrate.
