First, enter data involving multiple variables (described elsewhere).
In the “Analyses” section of the menu, select the “Regression -> Linear Regression” option (from the “Classical” section).

A set of options will then appear for you to choose the variables and statistics of interest.
Select the variables you wish to analyze by clicking on them in the left-hand box and then the arrow to move them into the right-hand boxes. Your Predictor (here “Outcome1”) should go under “Covariates” and your Outcome (here “Outcome2”) should go in as the “Dependent Variable”.
Output (with no descriptive statistics) will automatically appear on the right side of the window.

Scroll down to the section on “Statistics”. Check “Display -> Descriptives” and “Coefficients -> Estimates”.
Updated output will automatically appear on the right side of the window.
