outlier
Extreme numbers in the data as compared the the rest of the data are called OUTLIERS.
In terms of SQL, Skewness is an asymmetry in the distribution of the data values or how the value is distributed accross. Consider a table employees where you have millions of employee records and a column in that table which have either a value as 0 or 1 (F or T). Now consider out of one million records, the 1 value is applicable for only 2000 employees and the rest are having value as 0. This asymmetry or inproportionate data tells us that the column contains highly skewed data.
