Boxplot in Visualizations menu is not showing outliers

Box and whisker plots quartiles, and the band inside the box is always the second quartile (the median). But the ends of the whiskers can represent several possible alternative values, among them:

• the minimum and maximum of all of the data[1] (as in figure 2)
• the lowest datum still within 1.5 IQR of the lower quartile, and the highest datum still within 1.5 IQR of the upper quartile (often called the Tukey boxplot)[2][3][4] (as in figure 3)
• one standard deviation above and below the mean of the data
• the 9th percentile and the 91st percentile
• the 2nd percentile and the 98th percentile.

Any data not included between the whiskers should be plotted as an outlier with a dot, small circle, or star, but occasionally this is not done.
