Common Distribution Functions
After drawing a graph, you can use the P-CAL function to calculate an estimated p-value for
a particular x value.
The following is the general procedure for using the P-CAL function.
1. After drawing a graph, press
1
(P-CAL) to display the x value input dialog box.
2. Input the value you want for x and then press
w
.
• This causes the x and p values to appear at the bottom of the display, and moves the pointer
to the corresponding point on the graph.
3. Pressing
v
or a number key at this time causes the x value input dialog box to reappear so
you can perform another estimated value calculation if you want.
4. After you are finished, press
i
to clear the coordinate values and the pointer from the
display.
# Executing an analysis function automatically
stores the x and p values in alpha variables
X
and P, respectively.
