What is Boxplot/Box and Whisker plot

There are many graphical methods to summarize data like boxplots, stem and leaf plots, scatter plots, histograms and probability distributions. Out of these Boxplot is one of the simplest and most useful way to graphically show data.

Boxplot is useful in visually comparing the different data sets(preferably same size) taken from the same population. For example you want to compare performance of different teams doing similar work. We can also compare performance of different lots or different batches in a manufacturing environment.
