• V-Window settings for graph drawing are set automatically when the Setup screen’s “Stat

Wind” setting is “Auto”. Current V-Window settings are used for graph drawing when the “Stat
Wind” setting is “Manual”.

• After drawing a graph, you can use the P-CAL function to calculate an estimated

p

-value for

a particular

x

value. The P-CAL function can be used only after a Normal Probability Density,

Student-

t

Probability Density,

2

Probability Density, or

F

Probability Density graph is drawn.

The following is the general procedure for using the P-CAL function.

1. After drawing a distribution graph, press

!5(G-SOLVE) 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

J to clear the coordinate values and the pointer from the

display.

• Executing an analysis function automatically stores the

x

and

p

values in variables X and P,

respectively.

k Normal Distribution

• Normal Probability Density

5(DIST) 1(NORM) 1(Npd)

Normal Probability Density calculates the probability
density (

p

) for a specified single

x

-value or a list. When a

list is specified, calculation results for each list element are
displayed in list form.

• Normal probability density is applied to standard normal distribution.

• Specifying

= 1 and

= 0 specifies standard normal distribution.

Calculation Result Output Examples

When a list is specified

Graph when an

x

-value is specified

• Graphing is supported only when a variable is specified and a single

x

-value is entered as

data.
