In a distribution, when the tail extends more towards the right (assymetry)

Positive Kurtosis means that the distribution has hevier tails and sharper peak (around the maximum value.

Positive Skewnes

Positive Kurtosis

When the distribution is symetrical with respect to the position of the maximun value of the pex

Zero Skewnes

Skewness

Kurtosis

It means that the tails of the distribution are lighter and the peak around the maximum value is shorter.

Negative Kurtosis

In a distribution, when the tail exetnds towards the left (asymmetry).

The measurement of asymmetry or Kurtosis

Positive Skewnes

Kurtosis is a measure of the characterisc of the tails in a distribution. It gives information about how uniform the distribution is.

Characterization of a data ser

Graphical representation

Skewness is a measure of symmetry (or the lack of symmetry). A distribution, or data set, is symmetric with respect to the maximum value if one side is the mirror image of the other side.
