When you plot a dataset with
BoxWhiskerChart passing over the box in the plot with your mouse pointer shows some specifics about the dataset (min and max values, 1/4, 1/2, and 3/4 quartiles).
However, if you use
Median to calculate those values, they do not correspond. The values displayed by
BoxWhiskerChart are different. Does anyone have an explanation or is it simply a bug? Is it system specific (here 8.0.1 on OSX 10.6.8)?
data = RandomVariate[NormalDistribution[0, 1], 20] BoxWhiskerChart[data] Quartiles[data] Median[data]
