A standard normal distribution The main idea about the measure of dispersion is to get to know how the data are spread. e. 4 = 34. A mesokurtic There are three types of kurtosis: mesokurtic (similar to a normal distribution), leptokurtic (higher peak and heavier tails), and platykurtic (lower peak and lighter tails). Kurtosis is a statistical measure that describes the shape of a probability distribution’s tails relative to its peak. These distributions have heavy tails and a sharp peak, meaning extreme values are more common. Excess kurtosis Next, we subtract 3 from the sample kurtosis and get the excess kurtosis: \(\text {Excess kurtosis} = 0. Each type of kurtosis represents a different shape of a distribution. 7861 – 3 = -2. Therefore, the excess kurtosis is found using the formula below: Excess Kurtosis = Kurtosis – 3.
