Lower Quartile On A Box Plot. The data set is split into four groups as described above with the two groups in the middle from q1 to q3 making the box and the outside groups from. In this example the upper quartile is 20 and the lower quartile is 10.
We can represent the list of nine numbers from example 1 1 in such a box plot. Quartile 3 q3 14 16 2 15. A box plot is constructed from five values.
1 2 4 4 5 6 8 8 9 least value 1 lower quartile 3 median 5 upper quartile 8 highest value 9.
Quartile 3 q3 14 16 2 15. Hence the name box and whisker plot. Interpreting box and whisker plots the box and whisker plots below represent the body widths in inches of a a sample of jellyfish from two different species. Quartile 3 q3 14 16 2 15.
