Good news! You don’t have to know diddly-squat about statistics to be
able to come up with well-calculated conclusions and display them in
fancy graphs. All you need is the SPSS software and a bunch of numbers. This
book shows you how to type the numbers and produce brilliant statistics. It
really is as simple as that.
About This Book
This is fundamentally a reference book. Parts of the book are written as
stand-alone tutorials to make it easy for you to get into whatever you’re after.
After you’re up and running with SPSS, you can skip around and read just the
sections you need. You really don’t want to read straight through the entire
book. That way leads to boredom. I know — I went straight through everything
to write the book, and believe me, you don’t want to do that.
The book was designed to be used as follows:
1. Read the opening chapter so you’ll understand what SPSS is. I tried to
leave out the boring parts.
2. If SPSS is not already installed, you may need to read about installing it.
3. Read the stuff in Chapter 4 about defining variables and entering data. It
all makes sense after you get the hang of it, but the process seems to be
kind of screwy until you see how it works.
4. Skip around to find the things you want to do.
I would mention that you could skip the introduction, but it’s too late for that.
Besides, you’ll find some information here that could be useful.
This book is not about statistics. You will not find one explanation of statistical
theory or how calculations are performed. This book is about what you
can do to command SPSS to calculate statistics for you. The inside truth is
that you can be as dumb as a post about statistical calculation techniques
and still use SPSS to produce some nifty stats. You have my permission to
stop thinking right now.
However, if you decide to study the techniques of statistical calculation,
you’ll be able to understand what SPSS does to produce numbers. Your main
advantage in understanding the process to that degree of detail is that you’ll
be able to choose a calculation method that more closely models the reality
you are trying to analyze — if you are interested in reality.
About the Data
Throughout the book you will find examples that use data stored in files.
These files are freely available to you. The files are either installed with SPSS
in the SPSS installation directory at \Program Files\SPSS (unless you
chose another location during installation) or designed for this book and
available on the following Web site:
You can also find the files at my Web site:
Different kinds of files are available. Most are data files used to demonstrate
statistical calculations, and some are programming source code files. (Would
you believe you have a choice of three programming languages inside SPSS?)
Who This Book Is For
In general terms, this book is for anyone new to SPSS. No prior knowledge of
statistics or mathematics is needed or even expected. In specific terms, this
book was written with two groups in mind: students who are not majoring in
mathematics but are instructed to use SPSS and office workers who are
instructed to use SPSS.
For most people generating statistics, the complexity of using the software
becomes an obstacle. My purpose in writing this book is to show you how to
move that obstacle out of the way with minimum effort.
How This Book Is Organized
This book was written so you could read the first part, to get yourself started
with SPSS, and then jump around to the other parts as needed. SPSS is a huge
piece of software and you certainly don’t want to use everything.
The book is filled with step-by-step procedures that you can follow to see
how SPSS operates. After you use the provided sample data and step through
an example, you will understand how to apply the example to your data.
The parts of the book divide the information about SPSS into its major categories.
The chapters in each part further divide the information into smaller
Part I: The Fundamental
Mechanics of SPSS
The first part is the only one intended to be read straight through. You can
gloss over the installation, if you already have SPSS installed, but you will
need to familiarize yourself with the configuration options. You will come
across these configurations later and will need to know what can be changed.
This is the only place in the book where you will find a complete example —
starting with the entering of gathered data and ending with the generation of
Part II: Getting Data into and out of SPSS
Input can be tricky. Variables are defined by type and size and a few other
things. Part II shows you how to enter data through the main SPSS window
or load it from a file. In fact, you can read data from several kinds of files.
You can also write data to several kinds of files.
Part III: Graphing Data
In Part III you see how to produce graphs. A large part of the job performed
by SPSS is displaying data in graphic formats. SPSS can produce lots of different
kinds of graphs and maps. Fortunately, it’s an easy thing to do — you
simply select variable names and how you want them displayed.
Part IV: Analysis
Hidden down inside SPSS are lots of statistical methods. This thing manufactures
numbers like McDonald’s manufactures hamburgers. Part IV explains
how to manufacture the numbers you want.
Part V: Programming SPSS
with Command Syntax
Part V shows you how to use the SPSS internal command language. You can
record procedures in Command Syntax and execute them at will. You can do
anything with a Command Syntax program that you can do with the mouse
Part VI: Programming SPSS
with Python and Scripts
Part VI is BASIC talk about programming and scripting SPSS. Anything you
can do with Command Syntax or with the mouse and keyboard, you can also
do in the Python programming language. The scripting language of SPSS is
Part VII: The Part of Tens
Part VII is all about the add-ons for SPSS and the locations on the Internet
where you can find useful stuff.
