Now you need to tell the calculator to perform the regression on the two lists you want and where to copy the
equation. The syntax is:
- LinReg(a+bx)L 1 ,L 2 ,Y 1
Note: to find Y1, go to – [VARS], [Y-VARS], [FUNCTION], [Y1].
Notice that thervalue is about 0.8. This indicates that there is a fairly strong positive correlation between shoe size
and height.If you calculator does not display the r and r^2 lines then you need to go into the catalog and run the

You can then graph the scatterplot and the regression line:
The regression equation is:
