RENAME VARIABLES. RECODE famimpor (1,2 =1) (3,4 = 2). *Copy all string variables. After recoding we must respecify the value labels for all three variables. SPSS will sort the string values from highest to lowest (or vice versa) and then assign consecutive numbers to the values. In this quick tutorial, I demonstrate how to recode multiple string variables into numeric variables in SPSS. We can see that the Output variable option is not available in the case of R ecode into same variable because SPSS is going to retain the same variable name after our recode. This is as simple as recode v1 (1 = 2).The screenshot illustrates the effect. recode work_1 to work_8 (1 = 100). The variable length contains the length of the car in inches. Perhaps you want to change marital status so that married people and those in common-law relationships are counted as the same. 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? It also adds the string value as a label to the numeric value. Computing new variables. You'll soon notice that recoding from syntax is very simple and way, way faster than from the GUI. SPSS will assign numeric categories in alphabetical order. For example, the following data set has certain variables. For example, you may have measured people’s BMI (body mass index) as a continuous variable but may want to use it to create groups such as underweight, normal, overweight, obese. All other values remain unchanged, too. The new string values cannot be longer than the defined width of the target variable. There is a time variable called EVENT_TIME which records the time of day when each event occurred. You cannot recode numeric and string variables together. In SPSS you can create new variables with compute and you can modify the values of an existing variable with recode. How to recode multiple response variables in SPSS into a single categorical variable. EVENT_TIME is in hh.mm..ss format and ranges from 0:0:0 to 23:59:59. This tutorial will introduce you to the Variable View tab in SPSS, and teach you how to define variables – that is, specify their various parameters – within this view. In some cases you may want to recode a string variable into a numeric one. Defining the variables involves multiple processes and requires careful planning. If the INTO keyword is present (followed by a list of target variables) the result is stored into the target variable(s) (list= one or more variables), otherwise the variables are changed in place. This means that "under the hood", date-time variables are actually integers! All SPSS date-time variables, regardless of whether they're a date or a duration, are stored in SPSS as the number of seconds since October 14, 1582. The easiest way is just to type it in. However, you may wish to change a variable name in your present working file. Before going into that, we need to understand what recode can do for us. Note that you'll often want to apply or adjust some value labels after recoding. If you now run any results (means/frequencies) over these variables, you'll see that -9999 will be excluded from the results as if these were empty cells. In order to define a variable and set its parameters you need to get some data into SPSS. Remember that the SPSS variable name must be no more than 8 characters long, consist only of numbers and letters, and must start with a letter. Consider the example of a […] So we will learn when we use these two different functions. Therefore, you can't adddress a range of original and recoded variables by using the TO ALL keywords. There are two ways of recoding a variable. In SPSS, you have two options for collapsing and recoding continuous variables: the IF command and the RECODE command. After you’ve opened your data in SPSS and explored your data, you will likely want to recode some or all of your variables. You will also need to do this for the data to be added. Recode the data so that the batsmen are rank ordered by their number of runs, with the batsman with the highest runs given a code of "1" and the batsman with the lowest runs given a "5". The reason is that we rarely see these in practice and we didn't want to go into detail any further than we already did. We are currently using recode into different variable options because we want to preserve my original data set. 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. 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. For example, you could collapse salaries into a new variable containing salary-range categories. Posted on September 24, 2019 by Phyllis L. F. Rippey. This can easily be achieved with the "rename variable" command. For example, if you are grouping BMI you might use the name ’BMIgroup’. Note that after recoding the value labels are no longer correct.For more on this, see SPSS Recode - Cautionary Note. To create a new string variable, declare the variable with the STRING command before specifying it on RECODE. All examples use supermarket.sav. Follow the steps below to see how to do this. In the previous examples the original values were overwritten by the recoded values. This was done to ensure that our demographic variables can be analyzed together with the dependent variables. = 1) using PIN(1 1)(variable_1 to variable_5) I'm struggling to figure out the syntax for doing this in SPSS. An alternative is creating a new variable holding the recoded values. In this case, the FREQUENCIES can be applied to the other open dataset which may not contain a variable V1 and that typically triggers the error you see. 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. RECODE famimpor workimpo chldimpo (4,3=2) (ELSE=1). The Recode into Different Variables dialog box allows you to reassign the values of existing variables or collapse ranges of existing values into new values for a new variable. Make sure that you know precisely how to use SPSS when you’re playing around with variables. 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. My variables are codes assigned to each observation, where observations are turns of speaking in a discussion. Generally, if they are integers (1, 45, etc.) This feature is sometimes used when discretizing continuous variables: you can use LO (the lowest value that hasn't been previously addressed) as the lower boundary for each category. Example: The data given below represents a satisfaction rating out of 10 for a new service offered by a company. All values that are not 1 are left unaltered. If I understand correctly, you're not looking for RECODE because -9999 will not be changed into a different number. Choose Recode to access a drop-down menu. I would like to try out the examples as you present them but I'm not sure yet how to fix the dataset to try them out. Rather than using the recode command, use an if statement like this: RECODE famimpor (4=3). Value 6 is is left unaltered. You can recode numeric variables into string variables and vice versa. This is a tutorial on how to use the Recode into Same or Different Variables function in SPSS/PASW. In the Output Variable box, type in a name for the new (grouped) variable. I wish to create a categorical variable which represents the 3 shifts in which the events occurred. This creates a dichotomous variable with cut-off point between 2 and 3. Instead, try. Start by clicking on the Transform menu in the horizontal toolbar at the top of the screen. Posted on September 24, 2019 by Phyllis L. F. Rippey. Adding a Variable. I recommend going to Edit - Options (General Tab) and select "Open only one dataset at a time". 2007. A step by step guide to recoding AGE variables into generational groups in SPSS. Now that we're done, our new string variables are redundant so let's remove them. So we will take question no 1, 3, 7, 11, 13. Follow the steps below to see how to do this. To automatically recode variables: Click Transform > Automatic Recode. Th… 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. 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. I'm working with string variables in SPSS and encountered a problem in managing the data. I have an SPSS Statistics data file where each record represents an event that occurred in our work place. string c1 to c4 (a7). Enter the data in the SPSS Statistics Data Editor and name the variable ". Your comment will show up after approval from a moderator. For more, please see MISSING VALUES. 1 Choose Transform, Recode, Into Diﬀerent Variables. Select the string variable of interest in the left column and move it to the right column. Or we might want to make loglen which is the natural log of length. For example, Output variable name. 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. Enter a new name for the autorecoded variable in the New Name field, then click Add New Name. SPSS handout 3: Grouping and Recoding Variables Richard Buxton and Rosie Cornish. Click Transform > Recode into Different Variables. Recoding Variables in SPSS Statistics (cont...) Recode a given range in SPSS Statistics. After cloning, we can safely recode into the same variables, leaving the variable order intact and minimizing the need for dictionary modifications after recoding. This tutorial walks you through its main options, best practices and pitfalls. The syntax below looks a bit awkward but is not unusual. SPSS Chart Builder - Basic Steps. In this section we will see how to create new variables with compute. add files file */drop leis_1 to id. However, if you wish to RECODE these variables INTO new variables, for each variable a separate RECODE command line is necessary. Here we can use ELSE, which means “all values that were not previously addressed”. Click on T ransform > R ecode Into Different Variables... in the top menu. You can refer to our chi-square page. Published with written permission from SPSS Statistics, IBM Corporation. However, we can clone a variable with its dictionary information by combining RECODE with APPLY DICTIONARY. Published with written permission from SPSS Statistics, IBM Corporation. It isn’t unusual for this data to have been entered as string values — alphanumeric characters. Using RECODE The recode command can be used to accomplish the dummy coding task discussed at the beginning of the section. Variable_1 to Variable_5 are simply the percent of responses that are true (e.g. Before running any FREQUENCIES, make sure that supermarket.sav is open and that it's the only data file that's open. After you’ve opened your data in SPSS and explored your data, you will likely want to recode some or all of your variables. *Set measurement levels (needed for SPSS chart builder & Custom Tables). In this example we'll merge categories 1 and 2 of a variable v1. Place names and labels for the new variables, such as AgeGroup, then click the Change button to notify SPSS variables that you want to recode. You can recode numeric and string variables. *Remove (now) redundant variables. If so, it automatically declares the new string variables with the correct lengths that are needed for recoding into. Basically, they are the questions items of a scale, and there are 15 questions for measuring the different dimensions of personality. Join the 10,000s of students, academics and professionals who rely on Laerd Statistics. Next, RECODE usually used for CHI-SQUARE analysis steps to make your continuous data become categorical variables. In fact, if there is a missing value for one or more of the input variables, SPSS assigns the new variable a missing value. Do not forget to remember the Change button if not recode your command will fail. The new string values cannot be longer than the defined width of the target variable. It comes in handy for merging categories, dichotomizing continuous variables and some other tasks. 2 Put the variable you want to recode in the Input Variable → Output Variable box. Example: The data given below represents runs scored by 5 batsmen in a national-level match. In IBM SPSS Statistics, people frequently have categorical variables with lots of values. IF (score > 90) grade=4. After recoding we must respecify the value labels for all three variables. alter type s1 to s3 (f1) s4 (f6.3). That depends on what metric the original variables are in. Values are recoded only once by RECODE. Recoding Same Variable. In IBM SPSS Statistics, people frequently have categorical variables with lots of values. Background: I have two variables based on the same item of a survey. SPSS Inc. was acquired by IBM in October, 2009. *Set formats to percentages. three age groups). A crosstab confirms that categories 1 and 2 have been merged into 2. For quickly getting very proficient with RECODE it's recommended you follow along with the examples. This tutorial shows how to define variable properties in SPSS, especially custom missing values and value labels for categorical variables. The same is true for creating hirt1 from trialr1. Transfer the variable you want to recode by selected it and pressing the button, and give the new variable a name and label. Screenshots of every step is provided in an easy to follow tutorial of how to change or transform a list of ages into generational categories in SPSS The easiest way is to let SPSS automatically do it for you. Suppose we wanted to make a variable called length2 which has lengthsquared. Finally, note that RANK offers an alternative for discretizing variables.eval(ez_write_tag([[250,250],'spss_tutorials_com-large-leaderboard-2','ezslot_2',113,'0','0'])); A disadvantage of recoding into new variables is they don't have any dictionary information by default. formats work_1 to work_8 (pct8). We'll run FREQUENCIES right before and after recoding so we can check the results. The chart is a correlation of variables. Click on T ransform > R ecode Into Different Variables... in the top menu. This procedure will divide your sample into groups (e.g. How would you like to recode them? Clean Things Up. We therefore adjust the value label for 2 and remove the label for 1. Select the variable that needs to be recoded and enter new values for each response. The instructions below will show you how to recode variables. new string variable, declare the variable with the STRINGcommand before specifying it on RECODE. Recoding Variables in SPSS. Suppose you have a variable score that you need to collapse into five distinct categories in a new variable grade:. Perhaps you want to change marital status so that married people and those in common-law relationships are counted as the same. 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. Double-click on variable Rank to move it to the Input Variable -> Output Variable box. You really should avoid alphanumerics, though, and there is a simple way to make the data better: the Automatic Recode command. 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. 1. For this example, we want to code a variable to categorize level of education (educ_cat). Target variables must already exist. In SPSS, you can have 2 or more data files open at once (this is better avoided at all times). *Convert variables to numeric. IF (score <=90 AND score >= 80) grade=3. We'll do this by changing all values of 1 into 2. SPSS Recode Variable. Recoding and Creating Variables This chapter discusses different ways to recode variables in SPSS and ways to create new variables. The original value 3 remains unchanged. We can use the recode command to create the variable hit1. This is called listwise exclusion. Selecting the “Different” function reverses each score and includes them in an extra variable. Rather than using the recode command, use an if statement like this: As demonstrated, a descriptives by category table is a nice way to inspect these results. SPSS RECODE replaces data values with different values. 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 tutorial didn't cover some more exotic RECODE options. First, note that the new variables don't have any dictionary information at all. Variable definitions include a variable's name, type, label, formatting, role, and other attributes. Now we will again go to the Transform option and click on Recode into same variable option. *Required field. Recoding variables in SPSS can be rather problematic if you don’t quite know what you’re doing. A step by step guide to recoding AGE variables into generational groups in SPSS. For copying them from v2 into rec_v2 we'll use (ELSE = COPY). Second, the new variables are appended to the end of the active dataset. So the first variable (henceforth referred to as Var1) is the rating of whether the certain item is performed. Example: The data given below represents the scores of 10 students in a final examination. This module shows how to create and recode variables. You need to highlight the Runs variable in the left-hand box by clicking on it and then click the button to move it across to the Numeric Variable … Let’s use the auto data for our examples. Repeat for all other values, such that you are presented with the following screen: You will have returned to the previous screen and will now have to click on the. It isn’t unusual for this data to have been entered as string values — alphanumeric characters. Recode changes to codes of one or more variables (varlist1) according to a list of specifications enclosed in parentheses. SPSS Recode Example 2 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 by recode v4 to v6 (1,2,3 = 0) (4,5 = 1). The instructions below will show you how to recode variables. The tool also checks whether input variables are. In this section, we will learn Recode into Same or Different variables in SPSS using the Recode function. 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. This example shows some disadvantages of recoding into new variables. *For each variable, flag conversion failures: cases where converted value is system missing but original value is not empty.
