Skewness is the measure of symmetry, or more precisely, the lack of symmetry of a statistical distribution, or data set, on the left and right of the central axis.Kurtosis is the sharpness of the peak of a frequencydistribution curve, i.e., a measure of whether the data are heavy-tailed or light-tailed relative to a normal distribution.
Leptokurtic distributions are statistical distributions where there are extreme points along the X axis, resulting in a higher kurtosis than found in a normal distribution.
Mesokurtic distributions have a kurtosis of zero, matching that of the normal distribution, or normal curve, also known as a bell curve.
Platykurtic distributions have the peak of the curve comparatively flatter than that of normal distribution.
