Application Guide

Editing a Function
You can edit a function and update it in the work area.
1. You can edit a function by double-clicking the equation and then making changes as
required.
2. Press Enter after making all changes and the updates are displayed in the work
area.
Using Data&Statistics Functions in other Applications
Data&Statistics functions are stored as variables, and may be used in other
applications, in the same manner as any other variable. Support for all function types is
included.
Note: Function numbers increment to use the next available. If you have defined f1(x)
and f2(x) in Graphs&Geometry, the first function you create in Data&Statistics will
be f3(x).
Using Show Normal PDF
You can approximate data plotted in the Data&Statistics work area against the
normal probability density function. The tool overlays the normal probability density
function using the mean and the standard deviation of the data in the histogram.
To show the normal probability density function for plotted data:
1. Add a variable to the x-axis.
