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. So now we have enough data for the box and whisker plot.
Hence q1 2 4 2 3 the upper quartile q3 is equal to the median of the upper half. 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. Construct the box and whisker plot.
And the interquartile range is.
Quartile 3 q3 14 16 2 15. Quartile 1 q1 4 4 2 4. Q3 q1 15 4 11. Reading a box and whisker plot identify the median the lower and upper quartiles and the lower and upper extremes in the box and whisker plot below.
