SPSS Manual step by step – Via dropdown menu and the Syntax
Basic rules SPSS in general
1. American number formatting is used. So, where we use a comma in the Netherlands,
SPSS uses a period (E.G. the mean is 7.051). SPSS uses in groups of three digits in large
numbers comma’s (E.G. The N is 350,000).
 Be aware of this while answering questions and reporting information.
2. System-Missing data is when a respondent has a missing score on a variable (recognized
by “.”). User-Missing data has been assigned a value which refers to a missing score.
 Be aware that you don’t assign a number to the User-Missing data that is measured by
the scale of the question (E.G. a score between 0 and 10  Missing score of - / 999).
3. Be aware that your case number (the left column of numbers in data view), may not
always be the respondent number. In some surveys the respondent number is a separate
variable.
4. When you are selecting variables for any analysis, you will see the full label of that
specific variable. By right-clicking on the variables, you can select to see the variable name
instead of the label. Another option is to order the variables alphabetically or by
measurement level. This will make the variables easier to find and saves you time.
Basic rules SPSS about the Syntax
1. Whenever you follow the dropdown menu, if you click on “Paste” instead of “OK”. The
command appears in your Syntax window.
2. To run a command in the Syntax, the specific command must be selected.
3. Always end your command in the Syntax with a period.
4. Comments in the Syntax start with * and end with a period. After including the comments,
run the complete syntax (Dropdown menu: Run  All). If everything runs correctly, your
comments were correctly included.
