Kurtosis and Skewness


Kurtosis and Skewness are obscure statistical terms used to describe the graphical representation of the population. Kurtosis describes the rate of change of the curve and Skewness reflects the degree to which the curve is skewed the left or right. These terms will have more meaning after discussing distributions and curves.

It is a rare instance that a statistician has the luxury of dealing with the data of an entire population. Usually, we are forced into making assumptions of the population as a whole through data obtained from analyzing relatively small segments of the population called samples. A population sample makes use of slightly different nomenclature to describe its properties.
