Kurtosis is a statistic which is measuring shape of data distribution. It depicts the peaky-ness, or flatness, of the dataset.
If the distribution is very close to normal distribution, we say it is bell-shaped, and no kurtosis or kurtosis is zero.
A more flat-topped distribution is said to be platykurtic (Negative kurtosis), and a more peaky distribution is said to be leptokurtic (positive kurtosis).
