A box plot is a graph that not only helps us to see the distribution (or the shape) of the data, but it can also be used to compare two different groups to see if one differs from one another. As you carry on with math in high school you will become very familiar with these plots.
A box plot (or box and whisker graph) is a graph based on a 5 number summary of:
minimum
lower quartile
median
upper quartile
maximum.
Box plots are not always the same shape, they take different shapes depending on the 5 statistics.
When plotting a box plot it is plotted on an axis.
