Boxplots
Graphical Representation of the 5-number summary
Boxplots show the "five number summary" of the data, dividing the data into quarters (25%). From the left to right on the diagram: Minimum, first quartile (Q1), Median (Q2), third quartile (Q3), and maximum. Outliers, if present, are shown as separate dots or asterisks.

Definitions:
Minimum: The lowest value of the data set
First Quartile (Q1): Middle of the lower half of the data set. 25% of the data lies below this value and 75% lies above.
Median: Middle of the data set. Half the data (50%) lies below this value and half (50%) lies above.
Third Quartile (Q3): Middle of the upper half of the data set. 75% of the data lies below this value and 25% lies above.
Maximum: The highest value of the data set.

Two additional pieces of information that can be determined are:
The Interquartile Range (IQR) = Q3 - Q1
The Range = Max - Min
These pieces of information will show the extent to which the data is located near the center or near the extremes of the data set.
