For example, in the presence of outliers, any statistical test based on sample means and variances can be distorted. Estimated regression coefficients that minimize the Sum of Squares for Error (SSE) are very sensitive to outliers. ... Note that in the presence of one outlier, the median does not change in this example.

Statistical Tests in Breakdowns ... A single outlier is capable of considerably changing the slope of the regression line and, consequently, the value of the correlation, as demonstrated in the following example.

Researchers have proposed that hospitals with excessive statistically unexplained mortality rates are more likely to have quality of care problems. The U.S. Health Care Financing Administration uses this statistical "outlier" approach to screen for poor quality hospitals. ... Little is known, however, ... To our knowledge,

Grubbs' Test for Detecting Outlier ... Outliers make statistical analyses difficult. ... But statistical calculations can answer this question: If the values really were all sampled from a Gaussian distribution, what is the chance that you'd find one value as far from the others as you observed?

Three techniques for univariate outlier identification are: Extreme Studentized Deviate(ESD), the Hampel identifier and the Rousseeuw identifier. The latter two are robust statistical techniques. The purpose of the paper is to determine how these outlier identification techniques perform under varying conditions.
