Folk's "inclusive graphic skewness" (1968) is determined by the equation: ,where the phi values represent the same percentages as those for sorting.

The Skew Index helps us quantify chances the sky will actually fall and pull the market down with it. The Skew Index measures perceived tail-risk in the S&P 500. Tail-risk refers to a change in the price of the S&P 500 or a stock that would put it on the far edges (tails) of the normal distribution. The volatility skew is the difference in implied volatility (IV) between out-of-the-money options, at-the-money options, and in-the-money options.

Mathematically, the skewness formula is represented as, Skewness = ∑Ni (Xi – X)3 / (N-1) * σ3. where. X i = i th Random Variable. The online skewness calculator helps you to calculate skewness of a range of values. It is the measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. Code to add this calci to your website. Skewness Coefficient = 3 x (mean - median) / σ Where, σ=Standard deviation.

2016-02-01 Coefficient of Skewness: Skewness Coefficient also known as Pearson's Coefficient of Skewness or moment coefficient of skewness is the third standardized moment. It can be termed as Skew(X) and it is dependent on the mean, median and standard deviation of a given set of data.

For example the function: SKEW(B3:B102) will calculate skewness for the set of values contained in cells B3 through B102. Calculating Sample Skewness in Excel Skewness Calculator is a free online tool that displays the skewness in the statistical distributions.
