Casio FX-9750G, FX-9860GII IDisplaying the Calculation Results of a Drawn Paired-VariableGraph, ICopying a Regression Graph Formula to the GRAPH Mode

While the statistical data list is on the display, recall the Setup screen to specify a LIST (“List 1” through “List 26”) for “Resid List”. Calculated residual data is stored in the specified list.

The vertical distance from the plots to the regression model will be stored in the list.

Plots that are higher than the regression model are positive, while those that are lower are negative.

Residual calculation can be performed and saved for all regression models.

Any data already existing in the selected list is cleared. The residual of each plot is stored in the same precedence as the data used as the model.

IDisplaying 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 (CALC)(2VAR).

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

M........... mean of data stored in xList

3x .........	sum of data stored in xList
3x2 ........	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

N............ mean of data stored in yList

3y ......... sum of data stored in yList

3y2 ........	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
3xy ........	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

ICopying 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 6-10), press (COPY).

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

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

3.Press Uto 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.
