Box plots, used in descriptive statistics, are a convenient way of depicting data through their five-number summaries: the median, the variability of the data around the median, the skew of the data, the range of the data, and the size of the data set. The plot may be drawn either vertically or horizontally and may also indicate which observations, if any, might be considered outliers. The spacings between the different parts of the box help indicate the degree of dispersion and skewness in the data, and identify outliers.
The image above portrays what a typical version of a box plot looks like.
