Written and illustrated tutorials for the statistical software SPSS. The minimum for females working fulltime is 36. This is done with the STRING command. Your Syntax works in creating a new group that has the recoded variables. Create ID Number in SPSS. If I try to recode via the graphical interface it recodes and creates a new variable. if(gender = 0 & whours >= 36) fulltime = 1. the name for the new variable to create. For example, if the ID 100355 appears twice, the new variable will have values of 100355 and 100355_1 in the corresponding rows. Note, however, that RECODE becomes tedious insofar as we must correct more distinct values. or alternatively However, weeks only hold (24 * 7 =) 168 hours. END IF. In SPSS the command to do this is called Compute. [/box] So, this would create one new variable “vartotal” which would be the average of all 10 items. This module demonstrates how to subset data based on variables (using the keep and drop subcommands on the save command) and how to subset observations using the select ifcommand. And just as importantly, you’ll have documentation for exactly how you created them. If your variables are contiguous in the file you can use the SUM command using TO to specify the variables in simple syntax. Like so, our last example shows a different route to flag fulltime working males and females using different criteria. SPSS Missing Values Functions Typically, comments in SPSS syntax are color-coded with the color gray. In the second method, if any of the variables is missing, it will still calculate the mean. SPSS … First off, RECODE only replaces (ranges of) constants -such as 0, 99 or system missing values- by other constants. To create a new string variable within a DO IF—END IF structure, you must first declare the variable on the STRING command. Creating New Variables. Danish / Dansk Note that if you want to set a a variable equal to a missing value in a COMPUTE statement, use the syntax var=$SYSMIS. or the Syntax Reference Guide for a list of these functions.

There are at least two ways to create a string variable in SPSS. • Each row holds the data from a participant or “case” • Each column holds the data for a variable After specifying the information for each variable using I was wondering if there was a syntax to select all account names that include a certain string of text. This new variable will be used to identify and select only those cases that satisfy the conditional for all subsequent analyses. Second, RECODE can only set values based on a single variable. When the condition is true, the value for the string variable DIVISION is changed to TRANSFERRED but is truncated if the format for DIVISION is not at least 11 characters wide. Serbian / srpski And just as importantly, you’ll have documentation for exactly how you created them. So something like DO IF—END IF structures can be nested to any level permitted by available memory. The advantage of doing this is it disambiguates cases that might otherwise be confused – for example, if you had two John Smiths in your sample. In Syntax, you can define several different characteristics for each of your variables. Or we might want to make loglen which is the natural log of length. Next, we'll use a different RECODE command for males. SPSS Syntax to COMPUTE a new variable • Type the compute statement(s) with the new variable and the formula into the SPSS Syntax Window • Highlight the statement(s) • Click on the big green (run) arrow near the top of the window (under “Tools”) COMPUTE totalpet = reptnum + fishnum + mamlnum. I have a data base of patients which contain multiple variables as yes=1, no=0. To create a new string variable, declare the variable with the STRING command before specifying it on RECODE.

Bosnian / Bosanski Note that you can shorten the comman… how recode variable having overlapping range for gender. end if. A quicker way to do this would be: [box]MEAN(Var1 TO Var10). Then add the expression to the Numeric Expression field. The goal is to create a new variable, in the example it's Temperature on Day of Interest, that has the same value as the day it corresponds to (e.g. In the ‘Numeric Expression‘ box, enter the function ‘MEAN()‘. A good example is to add the suffix ‘_avg‘ to the variable name to signify that it is a mean. but you can use an IF condition involving multiple variables: There must be an END IF command for every DO IF command in the structure. In the next example, we show how to create a string variable in an existing data set. works fine. Suppose that for our first case VAR1=1 and VAR2 is system-missing. This gets us what we want however, as can be seen in the screenshot below, the new “Numeric_Zip” variable is currently set as a “Scale” variable. Two commands that you can use to create numeric variables are compute and if. You can have SPSS Create the variable now, which will immediately create the new variable in your dataset.
