WebThe mathematical formula for skewness is: a 3 = ∑ (x i − x ¯) 3 n s 3 a 3 = ∑ (x i − x ¯) 3 n s 3. The greater the deviation from zero indicates a greater degree of skewness. If the skewness is negative then the distribution is skewed left as in Figure 2.12. A positive measure of skewness indicates right skewness such as Figure 2.13. http://endmemo.com/statistics/skewness.php ciela bookstore
