Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data. From the smallest to the largest, the statistics plotted are:

  1. The minimum value
  2. The lower quartile (the value of the variable that is greater than a quarter of the observations)
  3. The median (the value of the variable that is greater than half the observations)
  4. The upper quartile (the value of the variable that is greater than three quarters of the observations)
  5. The maximum value.

(In slightly refined versions, outliers are separately identified).

The median is a measure of central tendency (average value). The difference between the quartiles is a measure of dispersion or spread around the average. The relative values of the five indicate whether or not the data set is skewed.
