Appendix Single-variable Statistical Calculation
<#040> Select single-variable (1-VAR) and input the following data:
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10} (FREQ: ON)
<#041> Edit the data to the following, using insert and delete:
{0, 1, 2, 3, 4, 5, 6, 7, 9, 10} (FREQ: ON)
<#042> Edit the FREQ data to the following:
{1, 2, 1, 2, 2, 2, 3, 4, 2, 1} (FREQ: ON)
• Examples <#043> through <#045> all use the same data as
Example <#042>.
<#043> Calculate sum of squares of the sample data and sum of
the sample data.
<#044> Calculate number of samples, mean, and population
standard deviation.
<#045> Calculate minimum value and maximum value.
Commands when Linear Regression Calculation
(A+BX) Is Selected
With linear regression, regression is performed in accordance with
the following model equation.
y = A + BX
The following are the commands that appear on the sub-menus that
appear when you select 4(Sum), 5(Var), 6(MinMax), or
7(Reg) on the STAT menu while linear regression is selected as
the statistical calculation type.
See Appendix <#046> for information about the calculation
formula used for each command.
