Description:

 

As described by USEPA (1992) The Skewness Coefficient indicates to what degree data are skewed or asymmetric with respect to the mean. Data from a normal distribution will have a skewness coefficient of 0, while asymmetric data will have a positive or negative skewness on whether the right- or left-hand tail of the distribution is longer or skinnier than the opposite tail.

 

Excessively skewed data may not be suitable for parametric analysis methods. ChemStat calculates the Skewness Coefficient for each well for the selected parameter.
