SPSS stands for Statistics Package for the Social Sciences and is probably the most popular general statistics packages in academia.

2 Important tips for beginners

Before you start analysing anything:

(1) Verify the data, e.g.

  • list minima and maxima for each variable or directly look at the raw data for small samples
  • Use for example: Analyze -> Descriptive Statistics -> Descriptives
  • Descriptives also may help you getting an idea about distributions: In the Options, tick all...

(2) Document the data and declare missing values (if needed)

  • Open the data editor -> variable view
  • Verify the type for each variable you plan to use (mostly it should just be "number")
  • Important: Declare measure, i.e. either nominal, Scale or ordinal. If you get this wrong, SPSS will not let do certain types of analysis or let you do it when it should not ...
  • Define a name (usually this should match questionnaire numbers), and label that defines the description
  • Important: Declare missing values. These will exclude a case from analysis. By default empty cells are already declared missing. Sometimes people use 999 as missing values and that should be declared !

(3) Configure working directory and turn on logging

  • Open Edit -> Options -> File Locations tab
  • Important: Tick Record syntax in journal. This will allow you to redo some analysis (and you can gain days of work if you understand how to do this).
  • Open the Output Labels tab and define how you would SPSS like to display the results. I usually want both variable (short) names plus the labels.

(4) Change language to writing language

  • Open Edit -> Options -> General tab

3 Impossible to enter the activation code because the popup window is too small

I find it quite mind-boggling that large software companies such as IBM or Adobe are not aware that many people do use computers with a good screen resolution (e.g. 3200X1600 on a laptop). Most Adobe programs are very difficult to use (even in 2016). SPSS itself works OK, except for the license activator. You cannot enter a licence number because the window is too small of whatever. Instead, you will have to run a command line program:

Under Windows, in the program manager, type cmd, then change into the directory where SPSS sits, e.g.

cd C:\Program Files\IBM\SPSS\Statistics\22
licenseactivator.ex you_auth_code_here

Another alternative is play with system font size, screen resolution, etc. Good luck !
