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

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…

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