What is compute in SPSS?
SPSS COMPUTE command sets the data values for (possibly new) numeric variables and string variables. These values are usually a function (such as MEAN, SUM or something more advanced) of other variables.
Where is the compute function 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.
How do I calculate a new variable based on values of other variables SPSS?
The condition would be ((var1 = 1) & (var2 = 1)) for example. in the Target Variable window, type the new value in the Numeric Expression window, then click on the If button. You can specify the condition (such as GENDER=1 or RACE=1 AND REGION=3) and then click on the Continue Button.
How do you sum variables in SPSS?
Answer. The Syntax for this would be: COMPUTE sum = SUM(v1,v2,v3,v4) . EXECUTE .
How do I compute variables in SPSS?
Apply a computation conditionally, so that a new variable is only computed for cases where certain conditions are met In this tutorial, we’ll discuss how to compute variables in SPSS using numeric expressions, built-in functions, and conditional logic.

How do I use if in SPSS?

How do you Compute surname prefix in SPSS?
compute surname_prefix = lower (surname_prefix). exe. SPSS can compute only existing string variables. For new string variables, we must first create new (empty) variables with the STRING command. After doing so, we can set their values with COMPUTE.
Why does SPSS create a string variable with an F format?
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. We first compute the mean over our 5 ratings but only for cases having at least 3 valid values.
