## Statistics - Multiple Regression

Multiple regression measures the error involved in using the regression line as a basis of
estimation. The regression line is created from the variables you choose (both dependent and
independent) and describes the average relationship existing between the variables within a
specified confidence level. You will choose one dependent variable and at least one independent
variable to run the regression test.

### To perform Multiple Regression:

- Select
**Statistics Multiple Regression** or use the keyboard combination Ctrl+Shift+R.
The *Regression analysis* dialog box will appear.
- In the listbox labeled
**Select questions**, select the question to use as
the dependent variable in the plot and move it into the **Dependent Variable **
window by using the right arrow button. Again from the All Questions listbox, choose
your independent variables and move them into the **Independent Variables**
window using the right arrow button.
- You can change the order of your independent variables by using the
**Up** and **Down**
buttons.
- Click
**Finish**. The mouse pointer will now be a cross-hair. Locate the
cross-hair where you would like the plot to appear and press the left-mouse button.
