I have question concerning box plot and it's whiskers. As I understood from
the description of the boxplot() function, if the range value is positive
the plot whiskers extend out from the box to the most extreme data points
defined by the values of the IQR times range (default 1.5). It suggests
that the upper and lower plot whiskers should be more less the same length.
What does it mean if they are not? How it's possible? I'm using default
value of the range.
