Enter a new name for the autorecoded variable in the New Name field, then click Add New Name. The IF command. The original value 3 remains unchanged. If the new values are shorter than the defined width of the target variable, the values are right-padded with blanks. Variable_1 to Variable_5 are simply the percent of responses that are true (e.g. Therefore, you can't adddress a range of original and recoded variables by using the TO ALL keywords. 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. You really should avoid alphanumerics, though, and there is a simple way to make the data better: the Automatic Recode command. Below we see summary statistics for length. *Set measurement levels (needed for SPSS chart builder & Custom Tables). You cannot recode numeric and string variables together. 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? A crosstab confirms that categories 1 and 2 have been merged into 2. Recoding Variables in SPSS. In the Output Variable area, … three age groups). Rather than using the recode command, use an if statement like this: Instead, try. 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. Record is a kind of function available in the SPSS Transform menu, which can help us in recoding the values that we assign to a variable. The top bar is the variable that correlates to large, the second is the variable that correlates to small. 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. This tutorial walks you through its main options, best practices and pitfalls. Make sure that you know precisely how to use SPSS when you’re playing around with variables. Written and illustrated tutorials for the statistical software SPSS. In fact, if there is a missing value for one or more of the input variables, SPSS assigns the new variable a missing value. Let’s use the auto data for our examples. The easiest way is just to type it in. Let's use the compute command to make a new variable that has the length in feet instead of inches, called lenft. (Don't forget to click on the New Name button after typing the variable name): Click on OK to perform the recoding. The most common cause of this error is a variable list that contains one or more undefined variables, and the variable list is not preceded by the optional VARIABLES keyword. We'll run FREQUENCIES right before and after recoding so we can check the results. SPSS will assign numeric categories in alphabetical order. *Convert variables to numeric. Published with written permission from SPSS Statistics, IBM Corporation. Example: The data given below represents runs scored by 5 batsmen in a national-level match. Keep in mind that you can RECODE and apply value labels to many variables at once. After cloning, we can safely recode into the same variables, leaving the variable order intact and minimizing the need for dictionary modifications after recoding. Next, RECODE usually used for CHI-SQUARE analysis steps to make your continuous data become categorical variables. So first we need clear about our problem. That is, there must be valid values for each input variable in order for the computation to work. The same is true for creating hirt1 from trialr1. Join the 10,000s of students, academics and professionals who rely on Laerd Statistics. Doing so with syntax is wayfaster than with the menu, especially if you want to recode many variables at once. The new string values cannot be longer than the defined width of the target variable. RECODE famimpor workimpo chldimpo (4,3=2) (ELSE=1). 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. After recoding we must respecify the value labels for all three variables. SPSS handout 3: Grouping and Recoding Variables Richard Buxton and Rosie Cornish. Follow the steps below to see how to do this. there is no need to explicitly recode them, you can just assume they … Before running any FREQUENCIES, make sure that supermarket.sav is open and that it's the only data file that's open. This creates a dichotomous variable with cut-off point between 2 and 3. Before going into that, we need to understand what recode can do for us. All values that are not 1 are left unaltered. Published with written permission from SPSS Statistics, IBM Corporation. Recoding variables in SPSS can be rather problematic if you don’t quite know what you’re doing. Recoding Variables in SPSS Statistics Introduction. After you’ve opened your data in SPSS and explored your data, you will likely want to recode some or all of your variables. This can easily be achieved with the "rename variable" command. The tool also checks whether input variables are. Rather than using the recode command, use an if statement like this: Suppose we wanted to make a variable called length2 which has lengthsquared. 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. For quickly getting very proficient with RECODE it's recommended you follow along with the examples. You can recode numeric variables into string variables and vice versa. Follow the steps below to see how to do this. *Required field. Recoding Variables in SPSS Menus and Syntax by Karen Grace-Martin 90 Comments SPSS offers two choices under the recode command: Into Same Variable and Into Different Variables. Read on to find out how. In a similar vein, HI can be used for the highest value.Optionally, users who have the SPSS Python Essentials installed can generate the crosstabs in a loop as shown in step 3B. This is as simple as recode v1 (1 = 2).The screenshot illustrates the effect. Select the variable that needs to be recoded and enter new values for each response. I recommend going to Edit - Options (General Tab) and select "Open only one dataset at a time". For example, suppose you have two variables (v1 and v2), and you wish to recode all cases of v2 to be equal to the system missing value where v1 is also system missing. This is also the reason that there's no point in specifying any old values after the ELSE keyword. We'll do this by changing all values of 1 into 2. Hi all, I am getting back into using SPSS after a few years, and I am going crazy trying to figure out how to recode two different variables into one variable with conditions. This is a tutorial on how to use the Recode into Same or Different Variables function in SPSS/PASW. After the variables have been entered, click on Transform and select “Recode into Same Variable” or different if things haven’t been coded in one take.
