Running a Regression on a Graphing Calculator
(To Find an Equation to fit the Data)
1. Turn your plots on: 2nd  StatPlot  select option 1  highlight ON  ENTER
2. Enter data into lists: STAT  select option 1 (Edit)  enter x-values in L1, y-values in L2
3. Create equation(s): 2nd  QUIT (to home screen)  STAT  highlight CALC  arrow down to
equation model of choice (LinReg, QuadReg, CubicReg, or QuartReg)  ENTER  ENTER
4. Graph equation with data: Y=  VARS  select Statistics (option 5)  highlight EQ  select
RegEQ (option 1)  ZOOM  select ZoomStat (option 9)
To make a prediction using your new equation:
2nd  TABLE  arrow up and down to find the value you are looking for
