k Displaying 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 k Copying 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. 6-21
