Negatively Skewed : For a distribution that is negatively skewed, the box plot will show the median closer to the upper or top quartile. A distribution is considered "Negatively Skewed" when mean < median. It means the data constitute higher frequency of low valued scores.

Webb2 apr. 2015 · The negative binomial distribution is a generalization of the Poisson for count data, with an additional parameter (k) which can describe over-dispersion . Small k implies a large variance and as k → ∞ the distribution tends to Poisson. We derive results first for the negative binomial distribution, then for the Poisson as a limiting case. WebbA negatively skewed distribution means the opposite: that the extreme data results are smaller. This means that the mean is brought down, and the median is larger than the mean in a negatively skewed distribution. Reducing skewness A data transformation may be used to reduce skewness.
