uTo specify statistical calculation data lists
You have to input the statistical data for the calculation you want to perform and
specify where it is located before you start a calculation. While the statistical data is
on the display, perform the following procedure.
2(CALC)4(SET)
The following is the meaning for each item.
1VarX .............. Specifies list where single-variable statistic
x values (XList) are
located.
1VarF .............. Specifies list where single-variable frequency values (Fre-
quency) are located.
2VarX .............. Specifies list where paired-variable statistic x values (XList)
are located.
2VarY .............. Specifies list where paired-variable statistic y values (YList)
are located.
2VarF .............. Specifies list where paired-variable frequency values (Fre-
quency) are located.
• Calculations in this section are performed based on the above specifications.

k Single-Variable Statistical Calculations
In the previous examples from “Histogram (Bar Graph)” to “Normal Distribution Curve,”
statistical calculation results were displayed after the graph was drawn. These were
numeric expressions of the characteristics of variables used in the graphic display.
The following operation produces the same values directly from the statistical data
list.
2(CALC)1(1VAR)
Now you can press f and c to view variable characteristics.
For details on the meanings of these statistical values, see “Displaying Single-Vari-
able Statistical Results”.
