For normally distributed data, the skewness should be about zero. For unimodal continuous distributions, a skewness value greater than zero means that there is more weight in the right tail of the distribution. WebbThe positively skewed distribution is a distribution where the mean, median, and mode of the distribution are positive rather than negative or zero, i.e., data distribution occurs more on the one side of the scale with a long tail on the right side.
