Taking the mean and median values of a data set can help reduce the influence of outliers. They are also called outlying observations.

Some studies [9][24] have used attribute correlation analysis to detect attribute outliers in a dataset, but the time complexity of these algorithms is very high.

Most of these techniques rely on the key assumption that normal objects belong to large and dense clusters, while outliers form very small clusters [6,7].
Krige and Magri (1982) studies the effects of outlier and data transformation on variogram estimates for a base metal and a gold ore body and observed that outliers can seriously distort and/or mask the real variogram patterns.
Gladwell argues that intelligence is not the only key to success, rather success is a combination of ability, opportunity and a particular environment in which the Outliers (extraordinary people) grow up.
