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. Display the statistical
data and then press 2(CALC)6 (SET).
The following is the meaning for each item.
1Var XList ....... specifies list where single-variable statistic
x values (XList)
are located
1Var Freq ....... specifies list where single-variable frequency values
(Frequency) are located
2Var XList ....... specifies list where paired-variable statistic x values (XList)
are located
2Var YList ....... specifies list where paired-variable statistic y values (YList)
are located
2Var Freq ....... specifies list where paired-variable frequency values
(Frequency) are located
• Calculations in this section are performed based on the above specifications.

k Single-Variable Statistical Calculations
In the previous examples from “Drawing a Normal Probability Plot” and “Histogram
(Bar Graph)” to “Line Graph,” statistical calculation results were displayed after the
graph was drawn. These were numeric expressions of the characteristics of
variables used in the graphic display.
These values can also be directly obtained by displaying the statistical data list
and pressing 2 (CALC) 1 (1VAR).
