You can subset your data by copying selected observations or variables to a separate data set. (You can select variables without losing selected observations by holding down the CTRL key while you click.) You can then analyze or save this new data set.

If no variables are selected, all variables are copied. If no observations are selected, all observations are copied. After you have selected observations or variables or both, select File →New →Data Set from Selected Data from the main menu. A new data table (Figure 4.15) appears, which contains only the selected subset of the original data.
