Ò (Histogram)
Histogram plots one-variable data. The Xscl window variable value
determines the width of each bar, beginning at Xmin. ZoomStat adjusts
Xmin, Xmax, Ymin, and Ymax to include all values, and also adjusts Xscl.
The inequality (Xmax N Xmin) à Xscl 47 must be true. A value that occurs
on the edge of a bar is counted in the bar to the right.
Õ (ModBoxplot)
ModBoxplot (modified box plot) plots one-variable data, like the regular
box plot, except points that are 1.5 ä Interquartile Range beyond the
quartiles. (The Interquartile Range is defined as the difference between
the third quartile Q3 and the first quartile Q1.) These points are plotted
individually beyond the whisker, using the Mark (› or + or ¦) you select.
You can trace these points, which are called outliers.
