How to do a regression equation on your calculator:
1. Note: if you want to find “r”, the correlation coefficient, you will need to turn
your Diagnostics On. This is a one-time thing. To this, press “2nd” and the “on”
button which will get you to the catalog. Then scroll down to the “DiaGnosticOn”
option. Push enter, then enter again.
2. Enter in your data:
a. Push the “STAT” button
b. Select 1:Edit and push enter
c. Enter your data into L1 and L2
3. Calculate your line/parabola/etc.:
a. Push the “STAT” button again
b. Arrow over to “CALC”
c. Choose the appropriate regression (#4. LinReg if you want to find a
linear regression equation.)
