χ Test χ
F Test F - and p -values are stored in variables F and P respectively.
The displays below show an example of what would happen if you perform a one-sample t -test with μ ≠ μ
(two-tailed test) and then draw a graph. The display on the right is an example when you select T > [Calculate
T Value].
When Two-Way ANOVA is performed
With Two-Way ANOVA, you can draw Interaction Plot graphs. The number of graphs depends on Factor B,
while the number of x -axis data depends on Factor A. The y -axis is the mean value of each category.
Selecting T > [Trace] displays a cross pointer on the graph (Trace). Pressing l or r moves the pointer
on the graph in the corresponding direction. When there are multiple graphs, you can use d and u to move
between graphs.
Using the Trace function automatically stores the last condition number of factor A to variable A and the mean
value of the last category to variable M, respectively.
Find a Confidence Interval
You can use the procedure below to find the upper and lower limits of the confidence interval from given sample
data and confidence level.
Operation Flow
1. Use List Editor to input the data and then create the list variables as required.
• For details about the input operation,
• See "Confidence Interval Types and List Variables" (page 51)
2. Use the procedure under
[Confidence Interval].
• This displays the Confidence Interval menu on the Setup tab.
3. Select the confidence interval type.
(1) Highlight line 2 of the Confidence Interval menu and then press O.
(2) From the menu that appears, select a confidence interval type.
To select this:
1-Sample Z Interval
2-Sample Z Interval

Select this menu item:
[Z Confidence Interval] > [1-Sample Z Interval]
[Z Confidence Interval] > [2-Sample Z Interval]
