If you are analysing your data using multiple regression and any of your independent variables were measured on a nominal or ordinal scale, you need to know how to create dummy variables and interpret their results. If more than one variable is labelled in a single command, use slashes (/) to separate specifications. Information here may no longer be accurate, and links may no longer be available or reliable. In this case, you want each bar of the histogram to represent a score on the Enjoyment scale. execute. Variables list. You now need to define what information will be displayed on the X-axis and the Y-axis of the graph. SPSS uses the standard set-up for a data matrix: Each row in the data set contains different variables for a single case (depending on what constitutes a "case", cases my extend over more than one row, but we need not discuss this here), and the different variables are represented by different columns of the data set. Matchendran. SPSS Variable Labels Syntax Examples The addition of a Der Befehl COMPUTE generiert eine neue Variable. The target variables must all be the same defined width; the source variables … RENAME VARIABLES (sex = gender) . Specific Skills . RENAME VARIABLE (varx = vara). This gives you a blank histogram template. MATCH FILES FILE=* /KEEP=var1 var2 var3 . For information on variable … Its most basic use is compute s2 = string (s1,f1). Depending on your use of the subset data you might even decide not to save the subset to an permanent file, but just run the syntax that creates the subset and perform your analyses.

If you want to define a more complicated condition, e.g. The command Into Same Variable replaces existing data with new values, but the command Into Different Variables adds a new variable to the data set. In order to define a variable and set its parameters you need to get some data into SPSS. Type [1] in the Value box, type [Female] in the Label box, and then click the Add button. Note: When listing the variable names in the syntax, the assigned measurement level must be given in brackets after each variable name: [s] for scale, [n] for nominal, [o] for ordinal. Scratch variables initialize to 0 for numeric variables and to a null string for string variables. Also, they are not reinitialized for each case; rather, they keep their current value when the next case is read. In this sense, they are equivalent to using the leave command. OR * The following Is for SPSS with Syntax. VARIABLE LEVEL M1 TO S11 (ORDINAL). So, SELECT the Enjoyment variable from the Variables List and drag and drop it to Syntax to define variable set.

You can use this command in many ways: To create a variable called total equal to the sum of variables v1, v2, v3, and v4, the syntax is: compute total = v1+v2+v3+v4. This is especially true when you’re creating a LOT of new variables, but even one or two can be quicker if you write the syntax code instead of menus. Multiple target variables are allowed.

If you use SPSS Syntax to produce the subset, keep the syntax file(s) that produced the subset, so you can rebuild the subset any time you need.
