41. Use of L-moments in place of moments provides a measure of skewness known as the L-skewness. 42. Use of L-moments in place of moments provides a measure of skewness known as the L-skewness . 43. Therefore, a positive skewness value indicates that the peak is located to the left with respect to the mean. 44. Other names for this measure are Galton's measure of skewness , the Yule Kendall index and the quartile skewness, 45. Other names for this measure are Galton's measure of skewness, the Yule Kendall index and the quartile skewness , 46. Historically, the third and fourth standardized moments ( skewness and kurtosis ) were some of the earliest tests for normality. 47. However it is possible that the sample skewness is larger, and then \ alpha cannot be determined from these equations. 48. Common measures of the shape of a distribution are skewness or kurtosis, while alternatives can be based on L-moments. 49. The parameter ? equals the difference between the distribution s mean and mode and can be viewed as unnormed measure of skewness . 50. So, an understanding of the skewness of the dataset indicates whether deviations from the mean are going to be positive or negative.
