Sampling error is one of two reasons for the difference between an estimate and the true, but

unknown, value of the population parameter. The other reason is non-sampling error. Even if a sampling process has no non-sampling errors (and therefore no bias) then estimates from different samples (of the same size) will vary from sample to sample. The sampling error for a given sample is unknown but when the sampling is random, the maximum likely size of the sampling error is called the margin of error.

Since sampling is typically done to determine the characteristics of a whole http://new.censusatschool.org.nz/faq/sampling-error-definition/ population, the difference between the sample and population values is considered a sampling error.[1] Exact measurement of sampling error is generally not feasible since the true population values are unknown; however, sampling error can often be estimated by probabilistic modeling of the sample.

An estimate of a quantity of interest, such as an average or percentage, will generally be subject to sample-to-sample variation.[1] These variations in the possible sample values of a statistic can theoretically be expressed as sampling errors, although in practice the exact sampling error is typically unknown. Sampling error also refers more broadly to this phenomenon of random sampling variation. Random sampling, and its derived terms such as sampling error, imply specific procedures for gathering and analyzing data that are rigorously applied as a method for arriving at results considered representative of a given population as a whole. Despite a common misunderstanding, "random" does not mean the same thing as "chance" as this idea is often used in describing si

Sociology Dictionary: Sociological Terms from A to Z Sociology Dictionary: S Index Sampling Error Share Pin Tweet Submit Stumble Post Share By Ashley Crossman Sociology Expert By Ashley Crossman Definition: Sampling error is an error that occurs when using samples to make inferences about the populations from which they are drawn. There are two kinds of sampling error: random error and bias.Random error is a pattern of errors that tend to cancel one another out so that the overall result still accurately reflects the true value. Every sample design will generate a certain amount of random error.Bias, on the other hand, is more serious because the pattern of errors is loaded in one direction or another and therefore do not balance each other out, producing a true distortion.
