WebbKurtosis. 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. Like skewness, kurtosis describes a particular aspect of a probability distribution. WebbThe mean and the median both reflect the skewing, but the mean reflects it more so.
