Skewness can come in the form of negative skewness or positive … WebKurtosis does not just measure tail heaviness. It also measures peakedness. A distribution that is similar in the tails but more peaked will tend to have higher kurtosis than one that is less peaked. Another way to think of kurtosis is as follows: Define the 'shoulders' of a density as being at μ ± σ.
