WebFeb 8, 2024 · Kurtosis is a statistic that measures the extent to which a distribution contains outliers. It assesses the propensity of a distribution to have extreme values within its tails. There are three kinds of kurtosis: leptokurtic, platykurtic, and mesokurtic. Statisticians define these types relative to the normal distribution. WebMay 2, 2024 · Key Takeaways.

It characterizes the extent to which the distribution of a set of … A distribution with negative excess kurtosis is called platykurtic, or platykurtotic."Platy-" means "broad". In terms of shape, a platykurtic distribution has thinner tails.Examples of platykurtic distributions include the continuous and discrete uniform distributions, and the raised cosine distribution.The most … See more In probability theory and statistics, kurtosis (from Greek: κυρτός, kyrtos or kurtos, meaning "curved, arching") is a measure of the "tailedness" of the probability distribution of a real-valued random variable.
