In the last step, we input these intermediate results into the skewness and kurtosis formulas. We obtain the following values: skewness = -0.3212 kurtosis = -0.7195 The negative value of the coefficient of skewness implies a slight skew to the left. It means that there are more short boys ...
Examples of probability distributions with low kurtosis values include theBernoulli distribution(for probability close to 50%; p = 50% generates the lowest possible kurtosis value, 1), and thediscrete uniform distribution. The formulas for skewness and kurtosis are as follows: You can compute both ...
Dear statalist, Can someone tell me the exact formulas used by Stata to calculate skewness and kurtosis. This question is because several types of skewness and kurtosis are defined in literature, and the terminology and notation are not consistent. Thanks Ari * * For searches and help try: *...
The histogram can give you a general idea of the shape, but two numerical measures of shape give a more precise evaluation: skewness tells you the amount and direction of skew (departure from horizontal symmetry), and kurtosis tells you how tall and sharp the central peak is, relative to a...

This calculator computes the skewness and kurtosis of a distribution or data set. Skewness is a measure of the symmetry, or lack thereof, of a distribution. Kurtosis measures the tail-heaviness of the distribution. A number of different formulas are used to calculate skewness and kurtosis. This...

XLSTAT proposes several coefficients of skewness and kurtosis. In this example, we will be referring to the Fisher coefficients which are not biased on the assumption that the data is normally distributed. Formulas can be found in the XLSTAT Help menu (click on the Help button in the dialog ...
While the skewness and kurtosis formulas appear to utilize all of the data, these shape statistics are essentially functions of the most extreme 5 percent of the data, and are heavily dependent upon the most extreme 1 percent of the data. They do not have any direct connection to the overall...
