4. Performing Statistical Calculations
All of the statistical calculations up to this point were performed after displaying a graph. The
following procedures can be used to perform statistical calculations alone.
S To 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
(CALC)(SET).
The following is the meaning for each item.
1Var XList.......location of single-variable statistic
x values (XList)
1Var Freq........location of single-variable frequency values (Frequency)
2Var XList.......location of paired-variable statistic
x values (XList)
2Var YList .......location of paired-variable statistic
y values (YList)
2Var Freq........location of paired-variable frequency values (Frequency)
• Calculations in this section are performed based on the above specifications.
I Single-Variable Statistical Calculations
In the previous example under “Displaying the Calculation Results of a Drawn Single-Variable
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 (CALC)(1VAR).
After this, pressing D or A scrolls the statistical calculation result display so you can view
variable characteristics.
For details on the meanings of these statistical values, see “Displaying the Calculation Results
of a Drawn Single-Variable Graph” (page 6-6).
I Paired-Variable Statistical Calculations
In the previous example under “Displaying the Calculation Results of a Drawn Paired-Variable
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.
