Hi ,everyone ,
I draw some boxplot figure with the command "boxplot".But in the
figure,there are some bubbles at the top part of the figure.
Can anyone tell me what the correct meaning of these bubbles?and how to
remove it?
Those are data points that are considered to be outliers. As to how
to remove them, that's a tricky question, more as to why than how.
The purpose of showing those points in a different way is to emphasize
that those points deserve special attention. You do not want to just
"make them go away".
