2. In the menu bar of the data file, click "Data" and select the "Add Variables" option in the "Merge File" option;
3. In the pop-up "Add Variables to XXX.sav" window, you can add variable data by opening the data set and the external SPSS Statistics data file.
4. Enter the "Variables added from "Multiple Merge";
5. After selecting the merging method, on the variable activity page of the window, confirm that the included variables are correct and click the "OK" button.
