In a left skewed distribution
WebIn the case where the longer tail is associated with smaller (or more negative) values, we say the distribution is skewed left or (negatively skewed). If the distribution is symmetric, we will often need to check if it is roughly bell-shaped, or has a different shape. In the case of a distribution where each rectangle is roughly the same height ... 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.
