That part of the total error (the estimate from a sample minus the population value) associated with using only a fraction of the population and extrapolating to the whole, as distinct from analytical [..]

The error introduced by the sampling process caused by making measurements on only a limited portion of a formation.

Erreur de sondage

The difference between the observed value of a statistic and the quantity it is intended to estimate.

The degree to which the results from the sample deviate from those that would be obtained from the entire population, because of random error in the selection of respondent and the corresponding reduc [..]

The difference between the observed values of a variable and the long-run average of the observed values in repetitions of the measurement.

In estimating from a random sample, the difference between the estimator and the parameter can be written as the sum of two components: bias and sampling error. The bias is the average error of the es [..]

The amount of error associated with a sample due to its deviation from the population

Deviations from expected ratios due to chance occurrences when the number of events is small. © 2005 by W. H. Freeman and Company. All rights reserved. Pierce, B. Genetics: A conceptual approa [..]

Error de Encuesta

Fluctuation in the value of a statistic that is calculated from different samples that are drawn from the same population. For example, if several different samples of 5 people are drawn at random fro [..]

The error in survey estimates that occurs because only a sample of the population is observed. Measured by sampling standard error.

The error in survey estimates that occurs because only a sample of the population is observed. Measured by sampling standard error.

Sampling error is the random variation that comes from sampling and cannot be eliminated but may be estimated.

an error arising from the fact that it is not statistically possible, short of a 100% sample, to select a sample, which corresponds perfectly to the population from which it is selected.  As the size of a sample increases, the magnitude of the sampling error decreases.  Sampling error differs from other kinds of statistical errors in that it occurs [..]

An error which arises because the data are collected from a part, rather than the whole of the population. It is usually measurable from the sample data in the case of probability sampling.

 The possible deviation in the reported finding of media audience research based on a sample from what might be the actual finding had a complete census been done. Usually reported as "+/-" the reported number.  

Part of the total estimation error of a parameter due to the random nature of the sample (ISO, 1977).

A change in gene frequencies between parents and offspring in a population that is due to the small size of each generation when populations themselves are small. Small samples usually do not exactly [..]

Survey error (variance and bias) due to observing a sample of the population rather than the entire population.

The amount of inaccuracy (i.e., random variation) in the estimate of some value of a population, caused by measuring only a portion of the population; by extension, the chance variation in the value of repeated samples from the population.

The estimated error range of the results of a survey using a sample.

An error that occurs because only part of the population is contacted directly. As with any sample, differences are likely to exist between the characteristics of the sampled population and the larger [..]
