Boxplot is a form of displaying cardinally scaled data displaying robust summary statistics as graphical elements.

A boxplot (or a box-and-whisker plot) is a mean of displaying cardinally scaled data. The graphic displays robust summary statistics of a given dataset. These include for the box: the median, the lower quartile and the upper quartile. The enclosed whiskers are not commonly defined and may display some figure tied to the inter quartile range (e.g. IQR x 1.5) or the maxima/minima. Sometimes outliers are displayed as well.

Boxplots may easily be created by most statistical packages such as:

boxplot(rnorm(100)) #For R
boxplot(randn(100)) %For Matlab
graph box variable  'For Stata
boxplot(data)       #For matplotlib (python)
boxplot(dataframe)  #For seaborn (python)
