An area sampling frame is an alternative to the most traditional type of sampling frames. A sampling frame is often defined as a list of elements of the...

quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within...

In statistics, a simple random sample (or SRS) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals...

by using area sampled masks. In this method, the number of bits set in a coverage mask for a pixel should be proportionate to the actual area coverage...

common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition...

out in each sampled cluster so that each unit sampled has the same probability of selection. An example of cluster sampling is area sampling or geographical...

more general concept of sampling frame includes area sampling frames, whose elements have a geographic nature. Area sampling frames can be useful for...

applies in particular when the sampled units are individuals, households or corporations. When a geographic area is sampled for a spatial analysis, bi-dimensional...

Nonprobability sampling is a form of sampling that does not utilise random sampling techniques where the probability of getting any particular sample may be calculated...

statistics research, snowball sampling (or chain sampling, chain-referral sampling, referral sampling) is a nonprobability sampling technique where existing...

Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required...

sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability...

time such a method has been used for a UK election. All of these polls use sample sizes substantially larger than typical national polls. These polls were...

A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions...

joined various local bands in the Portland area. It was singer-songwriter Noel Paul Stookey who encouraged Sample to try his hand at comedy. "You know, we’ve...

a population or sample and the standard error of a statistic (e.g., of the sample mean) are quite different, but related. The sample mean's standard error...

Slice sampling is a type of Markov chain Monte Carlo algorithm for pseudo-random number sampling, i.e. for drawing random samples from a statistical distribution...

would be parts of the curved area we want to sample from that could never be reached. Rejection sampling works as follows: Sample a point on the x {\displaystyle...

chosen randomly. By sampling both large areas (self-representing PSUs) and smaller areas (nonself-representing PSUs), the CPI-U sample represents the full...

A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into...
