The third central moment is the measure of the lopsidedness of the distribution; any symmetric distribution will have a third central moment, if defined, of zero. The normalised third central moment is called the skewness, often Gamma. A distribution that is skewed to the left (the tail of the distribution is longer on the left) will have a negative skewness. A distribution that is skewed to the right (the tail of the distribution is longer on the right), will have a positive skewness. For distributions that are not too different from the normal distribution, the median will be somewhere near MU <e2><88><92> Gamma * Sigma / 6; the mode about MU <e2><88><92> Gamma * Sigma / 2.
