É grátis para … Actually not sure you need to do this. The standard approach here is to add up all variables and multiply the last variable by 1, the second last variable by 10, the third last variable by 100 and so on. The first Recode dialog offers also an IF button that lets you perform a conditional RECODE, i.e. When you have two data files, you can combine them by merging them side by side, matching up observations based on an identifier. After recoding we must respecify the value labels for all three variables. A very simple example would be RECODE A (1 = 0) (2=1). This is basically what our SPSS Clone Variables Tool does for many variables at once.The tool also checks whether input variables are string variables. SPSS Syntax to combine categories of a qualitative variable using RECODE Example: The “chain” variable has three categories. three age groups). 2007. In it, I am recoding Educ, Years of Education, into 5 categories: Less than High School, High School Grad, Some College, Bachelor’s degree, More than college. This holds especially when you want to do calculations on ordinal variables under the Assumption of Equal Intervals.Note that we can't use AUTORECODE here because we don't want our values to follow the alphabetical order of our string values.

I have 2 variables, (VigPA, ModPA), each with a range of 0-1260 mins, and I need to recode them into one new variable (PAgroup) with specific conditions for each level. Required fields are marked *, Data Analysis with SPSS Now, you can't recode multiple variables into one with RECODE. This procedure will divide your sample into groups (e.g. It's free to sign up and bid on jobs. Numeric variables. All rights reserved. Define the value label (label define :::). Is it possible, if more than one choice is indicated , for the recode to use a priority system in choosing which one to specify in the new variable? Now, you can't recode multiple variables into one with RECODE. Unfortunately, copying the variable labels from the old to the new variables requires some more work but this can be automated with Python if desired. Click OK Or, you could do all of that in just a few lines of very logical syntax code: RECODE educ (12=2) (16=4) (MISSING=SYSMIS) (Lowest thru 11=1) (13 thru 15=3) (17 thru Highest=5) INTO Educ_cat. If you select multiple variables, they must be the same type (numeric or string). Conditional recodes . Also note that in the output, SPSS tells us which variable were used to create the new variables, how many cases were in the long data set (called "Cases In" in the Processing Statistics table), how many cases are in the wide data set (called "Cases Out"), and how many index values were created. In this section, we will learn about the Recode function in SPSS. We'll dichotomize variables v4 to v6 by changing values 1, 2 and 3 into 0 and values 4 and 5 into 1 as implied byrecode v4 to v6 (1,2,3 = 0)(4,5 = 1).Value 6 is is left unaltered. I have an spss datafile which separated responses from two groups of participants on the same survey question into two variables in SPSS (i.e. Statistical Consulting, Resources, and Statistics Workshops for Researchers.

Therefore, you can't adddress a range of original and recoded variables by using the TO ALL keywords. This creates a dichotomous variable with cut-off point between 2 and 3. If you continue we assume that you consent to receive cookies on all websites from The Analysis Factor. If you don’t have many variables to recode, say one or two, it’s not a big deal to use the menus (but at least paste the code, so you have a record of what you did later!). Why do you want to combine several variables into one in the first place? This is done by using the INTO keyword like sorecode v2 (1=2) into rec_v2.However, this doesn't tell which values rec_v2 should hold if v2 is not 1, resulting in lots of system missing values. And if you need to go back and change your coding scheme, say to combine two small categories, it’s a quick matter to update the code. When recode creates one or more new variables with a new classification, you may want to put value labels on these new variables. This example shows some disadvantages of recoding into new variables. In some cases you may want to recode a string variable into a numeric one. Want to learn more?

Each of the seven variables indicates a racial group, with 1=the student belongs to the racial group and 0=the student does not belong to the racial group. Recoded variables into new variables Just make sure that the number of input variables matches the number of output variables.This example uses LO THRU 3 which means “the lowest value through 3”. If you'd like to avoid that, see Combine Categorical Variables but I should add that it's somewhat technical (I should have built a tool for this syntax but I don't have the time for doing so).

Software . In the Set Definition list, select each variable you want to include in your new multiple dataset, and then click the arrow to move the selections to the Variables in Set list. The reason is I'm looking at twins and therefor have Click on Transform\Visual Binning; Move the variable to recode to the Variables to Bin box; In the section Binned Variable, type the name of the new categorical variable you will create Both are easy to do with syntax). In case of doubt we can always check the recoded variable against its clone and if necessary delete it and start over from a new clone. Recoding Into Same Variables replaces the values in the existing variable. To recode into different variables, click Transform > Recode into Different Variables.

So do not recode over an existing variable unless you are absolutely certain that the lost information will never be needed. We would like to match merge the files together so we have the dads observation on the same line with the faminc observation based on the key variable famid. E.g.

Now, you can't combine multiple variables into one with RECODE. Let me know if that gets you any further, ok? Usually, people code single variable with multiple responses and than recode it into several dummy-variables (0,1). This is from the General Social Survey data set that comes along with SPSS. After cloning, we can safely recode into the same variables, leaving the variable order intact and minimizing the need for dictionary modifications after recoding. RECODE famimpor (1,2 =1) (3,4 = 2). An alternative is creating a new variable holding the recoded values. 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. We'll do this by changing all values of 1 into 2. SPSS RECODE replaces data values with different values. My experience is that it's often done without any real need for it.
