Skewness: Skewness is defined as the degree of asymmetry about the central value of distribution. Skewness can be positive as well as negative. If the mean is greater than mode or the median, the skewness will be positive. If it is less Skewness will be negative.

Kurtosis: Kurtosis is defined as the degree to which a distribution is sharply peaked at its centre. Kurotosis is denoted by B2

Median: The median (M) is a statistics of location occasionally useful in biological research. St is defined as the value of the variable that has an equal number of items on either side of it. Thus, the median divides a frequency distribution of two halves.
