Viewing Single-variable Statistical Calculation Results Besides using a graph, you can also use the following procedure to view the single-variable statistics parameter values. To display single-variable calculation results (1) On the menu bar, tap [Calc] and then [One-Variable]. (2) On the dialog box that appears, specify the [XList] name and select the [Freq] setting (page 7-3-3, 7-3-4). (3) Tap [OK]. · This displays the Stat Calculation dialog box with the single-variable statistical calculation results described below. You can use the scrollbar to scroll the results. : sample mean sum of data sum of squares population standard deviation sample standard deviation sample size minimum first quartile median third quartile maximum mode* x: x2 : x: sx : n: minX : Q1 : Med : Q3 : maxX : Mode : ModeN : number of data mode items ModeF : data mode frequency * If "Mode = ModeStat" is shown on the Stat Calculation dialog box, it means that solutions are stored in the "ModeStat" system variable. To view the solutions, tap any list name cell on the Stat Editor window, input "ModeStat", and then tap . This will display the "ModeStat" system variable contents in the list. 20090601 7-7-2 Performing Statistical Calculations Viewing Paired-variable Statistical Calculation Results Besides using a graph, you can also use the following procedure to view the paired-variable statistics parameter values. To display paired-variable calculation results (1) On the menu bar, tap [Calc] and then [Two-Variable]. (2) On the dialog box that appears, specify the [XList] name and [YList] name, and select the [Freq] setting (page 7-3-3, 7-3-4). (3) Tap [OK]. · This displays the Stat Calculation dialog box with the paired-variable statistical calculation results described below. You can use the scrollbar to scroll the results. : sample mean of sample XList data sum of XList data sum of squares of XList data population standard deviation of XList data sample standard deviation of XList data sample size sample mean of sample YList data sum of YList data sum of squares of YList data population standard deviation of YList data sample standard deviation of YList data sum of products of XList and YList data x: x2 : x: sx : n: : y: y2 : y: sy : xy : minX : minimum of XList data maxX : maximum of XList data minY : minimum of YList data maxY : maximum of YList data 20090601 7-7-3 Performing Statistical Calculations Viewing Regression Calculation Results To view regression calculation results, tap [Calc] on the menu bar and then tap the type of calculation results you want. To view these calculation results: Linear regression Med-Med Quadratic regression Cubic regression Quartic regression Logarithmic regression Exponential regression (y = a·eb·x) Exponential regression (y = a·bx) Power regression Sinusoidal regression Logistic regression Tap this option: Linear Reg MedMed Line Quadratic Reg Cubic Reg Quartic Reg Logarithmic Reg Exponential Reg abExponential Reg Power Reg Sinusoidal Reg Logistic Reg · You can also use the [DispStat] option to display the last calculated statistical results. For details about regression calculation results, see "7-5 Graphing Paired-Variable Statistical Data". Residual Calculation Residual calculation calculates the distance (residual) between the regression model and an actual plotted point (y-coordinates) during regression calculations. ClassPad Operation (1) (2) Input the data you want into a list. (4) On the dialog box that appears, tap the [Copy Residual] down arrow button, and then select [On] or the list into which you want to copy the residual values. · Values assigned to the "residual" system variable shows the vertical distances between actually plotted points and the regression model. · A positive value indicates a plot that is higher than the regression model, while a negative value indicates a plot that is lower. · Whenever the [Copy Residual] setting is configured as described above, the ClassPad automatically assigns residual data to a system variable named "residual" when you perform a regression calculation. You can use the following procedure to view the current "residual" system variable values. 20060301 7-7-4 Performing Statistical Calculations To view "residual" system variable values (1) (2) (1) Tap here. (2) Tap here, and enter "residual". · To input lower-case alpha characters, tap the soft keyboard's (3) Tap . tab. Copying a Regression Formula to the Graph & Table Application You can use the following procedure to copy the calculated result of a regression formula to the Graph & Table application. There you can use Graph functions to edit and graph the formula, and perform other operations. ClassPad Operation (1) On the List window menu bar, tap [Calc] and then [Linear Reg].
