sampling (also known as grab sampling, accidental sampling, or opportunity sampling) is a type of non-probability sampling that involves the sample being...

sampling is also related to umbrella sampling in computational physics. Depending on the application, the term may refer to the process of sampling from...

also of importance: in survey sampling, use of sampling without replacement ensures the exchangeability of the sample with the population; in randomized...

In statistics, cluster sampling is a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population...

In statistics, sampling errors are incurred when the statistical characteristics of a population are estimated from a subset, or sample, of that population...

In statistics, 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...

In statistics, survey sampling describes the process of selecting a sample of elements from a target population to conduct a survey. The term "survey"...

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...

Acceptance sampling uses statistical sampling to determine whether to accept or reject a production lot of material. It has been a common quality control...

complicated sampling techniques, such as stratified sampling, the sample can often be split up into sub-samples. Typically, if there are H such sub-samples (from...

informative descriptive statistics, such as the sample range, do not make good test statistics since it is difficult to determine their sampling distribution. Two...
