This document discusses Karl Pearson's Coefficient of Skewness, a method for measuring the skewness of a data distribution. It provides examples of calculating the coefficient under individual and discrete series. For an individual series with data points ranging from 35 to 75 and a mean of 55, the coefficient is calculated to be 0.77, indicating positive skewness. For a discrete series with wage data, the coefficient is calculated to be -0.26, indicating negative skewness. The document also includes multiple choice questions to test understanding of skewness and the relationships between the mean, median and mode of a distribution.
