Correlation and Regression on the TI-82

Correlation/Regression:

To do statistics and lists, see the instructions written on calculator. This gives an overview and also some useful advice for working with statistics on calculator.

Calculating Values:

a) Enter the data. Place the x-values to list 1 and y-values to list 2.
b) Go to the Stats, Calc, and Setup screen.
c) Setup the 2-Var Stats and hence: Xlist = L1, Ylist = L2, Freq = 1.
d) Compute the Linear Regression (ax+b) (#5)

This screen will provide you the sample linear correlation coefficient r; that is the slope of regression equation a; and the y-intercept of regression equation b.

Simply record the value of r.

To write the regression equation, substitute the values of a and b to the equation ‘y-hat = ax+b’.

To determine the coefficient of determination, square r. We can determine the variable r beneath VARS, STATS, EQ and r (#6).
