WebbSkewness refers to the measure of the extent of asymmetry (wonkiness) of a distribution (usually of data) (Weisstein, n.d.). Different types of skewness exist. A positive skew happens when the wonky distribution of data has the “lump” of data occurring at the start, followed by a long “tail” – this is also called a right-skewed ...

Again, the mean reflects the skewing the most. Generally, if the distribution of data is skewed to the left, the mean is less than the median, which is often less than the mode.

Skewness indicates that the data may not be normally distributed. Often, skewness is easiest to detect with a histogram or a boxplot. These stem-and-leaf plots illustrate skewed data. The stem-and-leaf plot with right-skewed data shows wait times.
