four parts:The Minimum ValueThe Lower QuartileThe MedianThe Upper QuartileThe Maximum Value
NotesA long whisker or box indicates that the data
have a greater range. The values of the data are spread out.
A short whisker or box indicates the data have a lesser range.The values of the data in that part are
concentrated.
