15. The TI-83 and Lines of Regression (Best Fit) 1.Clear your lists (L1, L2) STAT -> 4 -> 2 nd -> 1 ->, -> 2 nd -> 2 -> CR 2.Enter your data…use the chart below: STAT -> CR -> (enter data) -> 2 nd -> Quit 3.Compute Equation STAT -> Rt Arrow -> 4 -> CR 4.Store Equation y = -> VARS -> 5 -> Rt Arrow -> Rt Arrow -> 1

16. 5. Set window based upon table 6. Graph Notes on Regression: Be conscious of your Stat Plot…don’t leave it on The + sign in stat plot is probably easiest to see This works universally for regression EXCEPT for the type of equation (linear, exponential, or…

17. Using the Regression Equation to Predict Values 1.Store any ‘valid’ value into x. # -> STO -> X -> CR 2.Compute corresponding value of y VARS -> Rt. Arrow -> CR -> CR -> CR
