What is string variables in SPSS?
String variables are one of SPSS’ two variable types. A simpler definition is that string variables are variables that hold zero or more text characters. String values are always treated as text, even if they contain only numbers. Some surprising consequences of this are shown towards the end of this tutorial.
What’s a string variable?
String variables — which are also called alphanumeric variables or character variables — have values that are treated as text. This means that the values of string variables may include numbers, letters, or symbols.
How do you analyze a string variable in SPSS?
How to Recode String Variables in SPSS
- Click on Transform -> Recode into Different Variables.
- Drag and drop the variable you wish to recode over into the Input Variable -> Output Variable box.
- Create a new name for your output variable in the Output Variable (Name) text box, and click the Change button.
What is a string variable in statistics?
String variables, simply speaking, are variables that contain not just numbers, but also other characters (possibly mixed with numbers). For instance, the European Social Survey stores information about the country where respondents were surveyed in variable cntry , which contains strings like “DE”, “ES, “LT” etc.
What is variable View in SPSS?
The Variable View tab displays information about the variables in your data. You can get to the Variable View window in two ways: In the Data Editor window, click the Variable View tab at the bottom. In the Data Editor window, in the Data View tab, double-click a variable name at the top of the column.
What is string type?
A string data type is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
How do you calculate variables in SPSS?
To compute a new variable, click Transform > Compute Variable. The Compute Variable window will open where you will specify how to calculate your new variable. A Target Variable: The name of the new variable that will be created during the computation. Simply type a name for the new variable in the text field.
Is age a string variable?
Variables come in two basic types, viz: numeric and string. Variables such as age, height and satisfaction are numeric, whereas name is a string variable.
How is a string variable converted to a string in SPSS?
SPSS’ string function converts numeric values to string values. Its most basic use is compute s2 = string(s1,f1). where s2 is a string variable, s1 is a numeric variable or value and f1 is the numeric format to be used.
What do you mean by Compute in SPSS?
SPSS COMPUTE Existing String Variable. In normal language, COMPUTE usually refers to operations on numbers. In SPSS, however, COMPUTE is used for setting the values of string variables as well. Keep in mind here that you can’t use numeric functions on string variables or vice versa.
How to calculate a target variable in SPSS?
To compute a new variable, click Transform > Compute Variable. The Compute Variable window will open where you will specify how to calculate your new variable. A Target Variable: The name of the new variable that will be created during the computation.
Why is 6 a missing value in SPSS?
This is because 6 is a user missing value and it’s used in a basic numeric function. If the variable that’s computed doesn’t exit yet, SPSS will create it as a numeric variable having an f format. One of the implications is that we can’t directly COMPUTE new string variables but we’ll get to that in a minute.
