Subject:      Boxplot question
Content-Type: text/plain; charset="iso-8859-1"

Hello,

 

When I generate a series of boxplots  (using the GUI, admittedly) there is a black band within each box which I would assume indicates the median.  I am a bit confused however, since the width of this band doesn't change relative to the size of the box/IQR.  This creates some visual confusion, since my boxes have different lengths/IQRs, and hence the band covers a significant portion of those with small IQRs.   Is there a way to have the boxplot generate a thin line to indicate the median versus this larger band?

 

Hope this is clear.

 

Cheers,

Christa
