WebA distribution is said to be skewed if the curve shifts to right or left from a normal bell-shaped distribution. The symmetrical curve has zero skewness. That is the normal distribution has a skew of zero. A skewed distribution has a tail at either of the sides. A tail refers to the tapering off on one side of the graph. WebIn a positively skewed distribution, the median and mode would be to the left of the mean. That means that the mean is greater than the median and the median is greater than the mode (Mean > Median > Mode) (Fig. 14.4).
