Older versions of SPSS
These chapters were written by Andy to cover IBM SPSS versions 10-24:
The current edition of this book was written using version 25 of IBM SPSS Statistics. IBM releases new editions of SPSS Statistics more often than Andy brings out new editions of this book, so, depending on when you buy the book, it may not reflect the latest version. This shouldn’t worry you because the procedures covered in this book are unlikely to be affected (see Section 4.12).
