Statview

box plot with outlier form StatView

Note: StatView does not follow the usual conventions for denoting the outlying points. StatView marks points with dots if the point is above the 95th percentile or below the 5th percentile. In this case, the lowest point is indeed an outlier.

JmpIn

box plot with outlier from JMP

Note: JMP's box plot has some additional features. The median is indicated by the horizontal line in the box. The red bracket beside the box indicates the shortest half (the most dense 50 percent) of the observations. The center of the diamond is the mean and the diamond extends to the end of the 95-percent confidence interval, which is explained in a later chapter.

Minitab
