Pearson's Skewness Coefficients

Given a Distribution with measured Mean, Median, Mode, and Standard Deviation $s$, Pearson's first skewness coefficient is

\begin{displaymath}
{3[{\rm mean}]-[{\rm mode}]\over s},
\end{displaymath}

and the second coefficient is

\begin{displaymath}
{3[{\rm mean}]-[{\rm median}]\over s}.
\end{displaymath}
