Example Of Kurtosis In Statistics. Sample kurtosis is always measured relative to the kurtosis of a normal distribution which is 3. The kurtosis of s 0 94 i e.
Second moment is calculated using the formula given below. Statistics kurtosis the degree of tailedness of a distribution is measured by kurtosis. For one example the beta 5 1 has an infinite peak and has negative excess kurtosis.
The population kurtosis is 1 114.
Skr 1 n n i 1 xi x 4 s4 s k r 1 n i 1 n x i x 4 s 4. So the sample is moderately less peaked than a normal distribution. Mesokurtic distributions have excess kurtosis of zero. Skr 1 n n i 1 xi x 4 s4 s k r 1 n i 1 n x i x 4 s 4.
