SOLVED:The English statistician Karl Pearson (1857-1936) introduced a formula for the skewness of a distribution. P=(3(x̅-median))/(s) Pearson's index of skewness Most distributions have an index of skewness between -3 and 3 . When P>0, the data are skewed right. When P<0, the data are skewed left. When P=0, the data are symmetric. Calculate the coefficient of skewness for each distribution. Describe the shape of each. (a) x̅=17, s=2.3, median =19 (b) x̅=32, s=5.1, median =25 (c) x̅=9.2, s=1.8

Skewness in Statistics | Definition, Formula & Examples

SOLVED: Pearson Coefficient of Skewness: A measure to determine the skewness of a distribution is called the Pearson coefficient of skewness (PC). The formula is PC = 3 - (X - MD)/s. The values of the coefficient usually range from -3 to 3. When the distribution is symmetric, the coefficient is zero; when the distribution is positively skewed, it is positive; and when the distribution is negatively skewed, it is negative.Using the formula, find the coefficient of skewness for each distribution
