Random samples in SPSS
Two methods are available to produce random samples in SPSS using syntax.
Cutting and pasting the syntax in the box below and then running in a SPSS syntax window produces a 10% sample (without replacement). The sample will be contained in a file called tenpc.sav on the C: drive.
temporary. sample .10. save outfile="c:\tenpc.sav".
The syntax in the box below produces a sample of size 500 from a total sample of 5000 (without replacement) and saves in a file called tenpc.sav on the C: drive.
temporary. sample 500 from 5000. save outfile="c:\tenpc.sav".
