A Box Plot is a method that was created in order to display a five-number data summary. Another common name for this graph is a "box & whisker plot". Within the box plot is the median, the upper and lower quartiles and the minimum and maximum data values. Within the actual box itself lies the middle 50% of the data. The upper edge of the box contains the 75th percentile of the data, and the lower edge contains the 25th percentile of the data. The line within the box displays the median value. The very end lines show the minimum and maximum data values.
The Box Plot shown represents the distribution of salaries of employees of a certain company. From looking it is clear that the salary range is very large. The highest earner earns around $97,000, while the bottom earner brings in about $14,000. The majority of employees earns a salary closer to the lower end of this range, with 50% of employees earning somewhere between $25,000 and $65,000.
