The TI-83 and Lines of Regression (Best Fit)

1. Clear your lists (L1, L2) STAT -> 4 -> 2nd -> 1 -> , -> 2nd -> 2 -> CR

2. Enter your data…use the chart below: STAT -> CR -> (enter data) -> 2nd -> Quit

x 0 1 2 3 4 5y 8 8.37 8.75 9.16 9.88 9.91

3. Compute Equation STAT -> Rt Arrow -> 4 -> CR

4. Store Equation y = -> VARS -> 5 -> Rt Arrow -> Rt Arrow -> 1

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…

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
