#What are the naming rules for spss variables?
spss variable naming rules are:
1. Open the SPSS data editing window, click "Variable View" in the view conversion bar to enter the variable view page .
#2. Define the variable name: Select the name cell of a variable and click to edit the variable name. If you enter data directly without editing the variable name in advance, it will be displayed as shown below. From a technical point of view, this can also be done, but it will be very confusing when analyzing the variables specifically, and it will be difficult for others to understand.
#3. Define the variable type: Select the "Type" cell of a variable, click to pop up the following dialog box, select the type corresponding to the variable. For example: the "gender" variable generally chooses a string, which is only used for classification, while the age variable generally chooses "numeric value", which is used for statistical analysis and can calculate the average age.
4. Definition of width and number of decimal places: The definition of width refers to the width of the variable, that is, the number of integer digits of the variable. Generally, the system default is 8; and the number of decimal places Refers to the decimal place of the variable, the system default is 2. As you can see, string variables have no decimal places.
#5. Variable label definition: Select the "label" cell of a variable and directly enter the corresponding content to define the variable. Its function is to further explain and illustrate the variable name to avoid forgetting and confusion.
6. Variable value label definition: often used. Select the "value" cell of a variable and click to bring up the following dialog box. For example: when defining the gender variable value, 0 represents a girl and 1 represents a boy.
