Chapter 7: Statistics Application

• Clear list variable data from list1 through list6 and initialize Stat Editor 

window contents .................................................................................................................. Edit - Clear All

• Convert a mathematical expression in the currently selected cell to a decimal value ................................9

• Display two, three, or four columns in the Stat Editor window* ...................................................S / D / F

* You can also specify the number of display columns using the [Cell Width Pattern] setting on the [Special] tab 

of the Graph Format dialog box (page 36).

Up to nine graphs, including single-variable data and paired-variable data statistical graphs can be drawn 
simultaneously ([SetGraph] - [StatGraph1] to [StatGraph9]).

In addition to graphs that can be drawn using [Set Graph], the graphs below can also be drawn at the same 
time.

• Regression graphs (using [Linear Reg] and other regression commands on the [Calc] - [Regression] menu)

• Function graphs (using the Graph & Table application’s Graph Editor window)

Drawing a statistical graph requires the following basic steps: (1) preparation of the list data to be used; (2) 
selection of the graph type and other graph settings; (3) drawing of the graph.

u To prepare list data for statistical graphing

Prepare the list data using one of the patterns shown below.

•  Single-variable data is data that consists of a single value. If you are trying to obtain the average height of the members 

of a single class, for example, the single-variable would be height. With paired-variable statistical data there are two 
values for each data item. An example of paired-variable statistical data would be the change in size of an iron bar as its 
temperature changes. One variable would be temperature, and the other variable is the corresponding bar size. 

•  A list of frequency values can contain non-zero integers and decimal values. In the case of a MedBox (page 132) or MedMed 

line (page 133), however, a frequency list can contain positive integers only. Non-integer values (such as those with a 
decimal part) cause an error during statistical calculations.

•  If you created user list data with another application, open it in the Stat Editor window. For more information, see “To 

open an existing list” (page 129). You can specify a list displayed in the Stat Editor window as data to be used for statistical 
graphing.

•  You can display up to 99 lists on the Stat Editor window.
