Single-Variable Statistical Calculations
In the previous examples from “Histogram” to “Normal Distribution Curve,” statistical
calculation results were displayed after the graph was drawn. These were numeric
expressions of the characteristics of variables used in the graphic display.
The following operation produces the same values directly from the statistical data
list.
