Calculating and Graphing Paired-Variable Statistical Data

kSelecting the Regression Type

After you graph paired-variable statistical data, press 1(CALC). Then you can use the function menu at the bottom of the display to select from a variety of different types of regression.

•{2VAR} ... {paired-variable statistical results}

•{X}/{Med}/{X^2}/{X^3}/{X^4}/{Log}/{Exp}/{Pwr}/{Sin}/{Lgst}

... {linear regression}/{Med-Med}/{quadratic regression}/{cubic regression}/{quartic regression}/{logarithmic regression}/{exponential regression}/{power regression}/ {sinusoidal regression}/{logistic regression} calculation and graphing

kDisplaying Regression Calculation Results

Whenever you perform a regression calculation, the regression formula parameter (such as a and b in the linear regression y = ax + b) calculation results appear on the display. You can use these to obtain statistical calculation results.

Regression parameters are calculated as soon as you press a function key to select a regression type, while a graph is on the display.

kGraphing Statistical Calculation Results

While the parameter calculation result is on the display, you can graph the displayed regression formula by pressing 6(DRAW).
