Kurtosis measure the shape of distribution or in other word kurtosis measures the peakness of its frequency distribution
∴The measures of kurtosis is given by:
\(\beta_2=\frac{\mu_4}{\mu_2^2}\)
If the curve has much flatness then the normal curve is called a Leptokurtic curve
If the curve has lesser flatness than the normal curve then it is called a platykurtic curve
If the curve is equally flat as a normal curve then it is called a Mesokurtic curve
