When we talk about kurtosis in statistics, we’re focusing on two main aspects of a data distribution: tailedness and peakedness. Tailedness in kurtosis refers to the frequency and extremity of outliers in a dataset. Outliers are those unusual values that fall far from the majority of the dat...
In statistics, we use the kurtosis measure to describe the “tailedness” of the distribution as it describes the shape of it. It is also a measure of the “peakedness” of the distribution. A high kurtosis distribution has a sharper peak and longer fatter tails, while a low kurtosis distr...
Finally, this article is intended to show you how to compute the median, mode, skewness, and kurtosis statistics using Access, and is not meant as a primer in the statistical constructs or methods themselves. For readers interested in learning more about the statistics themselves, and how they...

Kurtosis and spread Kevin P. BalandaHelen MacGillivray Canadian journal of statistics Mar 1990 An increase in kurtosis is achieved through the location- and scale-free movement of probability mass from the “shoulders” of a distribution into its centre and tails. We introduce a coherent structure...

While 24 of the 25 values remain the same, with each change in the last value the skewness and kurtosis statistics drop. As long as the point being moved is the most extreme point its value has a major impact upon the shape statistics. In the last two data sets, as the point being ...
