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...

distribution of stars in space is uniform. In particular, it causes measured parallaxes to stars to be larger than their actual values. The bias towards measuring...

practice, biased estimators (with generally small bias) are frequently used. When a biased estimator is used, bounds of the bias are calculated. A biased estimator...

and engineering, a bias is a systematic error. Statistical bias results from an unfair sampling of a population, or from an estimation process that does...

were no bias, the ratio of the estimated to known standard deviation would be unity. Clearly, for modest sample sizes there can be significant bias (a factor...

In statistics, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations. In statistical surveys, when...

In some cases biased estimators have lower MSE because they have a smaller variance than does any unbiased estimator; see estimator bias. Consider the...
