High kurtosis distribution
Web9 de nov. de 2024 · 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 distribution has a more rounded pean and shorter thinner ... WebThe last descriptive statistic is kurtosis, which provides information for the degree of peakedness of a data distribution. Peakedness in a data distribution is the degree to which data values are concentrated around the mean. Datasets with high kurtosis tend to have a distinct peak near the mean and tend to decline rapidly, and have heavy tails.

WebKurtosis is a statistical measure that quantifies the degree of peakedness of a distribution. It is a measure of how often values in the distribution fall close to the mean, and how often they fall far away from the mean. A distribution with a high kurtosis is said to be "peaked", while a distribution with a low kurtosis is said to be "flat".
