[Important notice]
SPSS Inc. was acquired by IBM in October, 2009. As a result, the organization’s name changed immediately and is now “SPSS, an IBM company". Materials posted up to 20 March 2010 use release 15: materials added after 21 March 2010 may also use release 18 (PASW 18). The user interface is different in appearance (see comparative screenshots), but all the exercises and examples should still work with earlier versions of SPSS. If not, I shall post a warning notice and a workaround.
