kDisplaying the Calculation Results of a Drawn Paired-Variable Graph

Paired-variable statistics can be expressed as both graphs and parameter values. When these graphs are displayed, the paired-variable calculation results appear as shown below when you press 1(CALC)1(2-VAR).

• Use c to scroll the list so you can view the items that run off the bottom of the screen.

o........... mean of data stored in xList

Σx .........

sum of data stored in xList

Σx2 ........

sum of squares of data stored in

 

xList

σx ..........

population standard deviation of

 

data stored in xList

sx ..........

sample standard deviation of

 

data stored in xList

n........... number of data

p............ mean of data stored in yList

Σy ......... sum of data stored in yList

Σy2 ........

sum of squares of data stored in yList

σy ..........

population standard deviation of data

 

stored in yList

sy ..........

sample standard deviation of data

 

stored in yList

Σxy ........

sum of the product of data stored in

 

xList and yList

minX......

minimum of data stored in xList

maxX.....

maximum of data stored in xList

minY......

minimum of data stored in yList

maxY.....

maximum of data stored in yList

kCopying a Regression Graph Formula to the Graph Mode

You can copy regression formula calculation results to the Graph mode graph relation list, and store and compare.

1. While a regression calculation result is on the display (see “Displaying Regression Calculation Results” on page 6-16), press 5(COPY).

• This will display the Graph mode graph relation list.*1

2. Use f and c to highlight the area to which you want to copy the regression formula of the displayed result.

3. Press w to save the copied graph formula and return to the previous regression calculation result display.

*1 You cannot edit regression formulas for graph formulas in the Graph mode.
