On top of that, all variables still have their original names and order. *Convert variables to numeric. 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". Written and illustrated tutorials for the statistical software SPSS. Start by clicking on the Transform menu in the horizontal toolbar at the top of the screen. Select the string variable of interest in the left column and move it to the right column. In the Output Variable area, … This is called listwise exclusion. MISSING VALUES [VARIABLE NAMES GO HERE] (-9999). RENAME VARIABLES. Assume we have variable famimpor with values 1, 2, 3 and 4, measuring how important having a family is for the respondent. 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. This tutorial shows how to define variable properties in SPSS, especially custom missing values and value labels for categorical variables. However, you may wish to change a variable name in your present working file. In order to define a variable and set its parameters you need to get some data into SPSS. That is, there must be valid values for each input variable in order for the computation to work. IF (score <=90 AND score >= 80) grade=3. RECODE famimpor workimpo chldimpo (4,3=2) (ELSE=1). Example: The data given below represents runs scored by 5 batsmen in a national-level match. There is a time variable called EVENT_TIME which records the time of day when each event occurred. In this quick tutorial, I demonstrate how to recode multiple string variables into numeric variables in SPSS. How would you like to recode them? For example, Output variable name. Posted on September 24, 2019 by Phyllis L. F. Rippey. Target variables must already exist. 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 Use our expert help to get to grips with the troublesome task of changing variables. Select the variable that needs to be recoded and enter new values for each response. *Set formats to percentages. The new string values cannot be longer than the defined width of the target variable. For quickly getting very proficient with RECODE it's recommended you follow along with the examples. 1. What do these variables measure and how are they currently coded? In this example we'll merge categories 1 and 2 of a variable v1. The same is true for creating hirt1 from trialr1. So we will learn when we use these two different functions. Follow the steps below to see how to do this. If so, it automatically declares the new string variables with the correct lengths that are needed for recoding into. Before going into that, we need to understand what recode can do for us. 5. We therefore adjust the value label for 2 and remove the label for 1. Now that you have mastered the art of creating new variables, you need to recode them to address our research question about gender and party identification. So the first variable (henceforth referred to as Var1) is the rating of whether the certain item is performed. Note that after recoding the value labels are no longer correct.For more on this, see SPSS Recode - Cautionary Note. In SPSS you can create new variables with compute and you can modify the values of an existing variable with recode. So we will take question no 1, 3, 7, 11, 13. The chart is a correlation of variables. Enter a new name for the autorecoded variable in the New Name field, then click Add New Name. Recoding variables in SPSS can be rather problematic if you don’t quite know what you’re doing. Values are recoded only once by RECODE. Variable_1 to Variable_5 are simply the percent of responses that are true (e.g. 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. RECODE famimpor (4=3). SPSS handout 3: Grouping and Recoding Variables Richard Buxton and Rosie Cornish. To automatically recode variables: Click Transform > Automatic Recode. All other values remain unchanged, too. In fact, if there is a missing value for one or more of the input variables, SPSS assigns the new variable a missing value. Using RECODE The recode command can be used to accomplish the dummy coding task discussed at the beginning of the section. If I understand correctly, you're not looking for RECODE because -9999 will not be changed into a different number. recode s1 to s4 (else = copy) into c1 to c4. The easiest way is just to type it in. 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. The old and new value pairs are read from left to right and an old value that's already been addressed will be ignored if it's addressed again. For more, please see MISSING VALUES. We can use the recode command to create the variable hit1. Make sure that you know precisely how to use SPSS when you’re playing around with variables. Recoding Same Variable. SPSS will sort the string values from highest to lowest (or vice versa) and then assign consecutive numbers to the values. Posted on September 24, 2019 by Phyllis L. F. Rippey. Perhaps you want to change marital status so that married people and those in common-law relationships are counted as the same. newval specifies the new values to replace oldvalues. For example, if you are grouping BMI you might use the name ’BMIgroup’. This creates a dichotomous variable with cut-off point between 2 and 3. We'll do this by changing all values of 1 into 2. 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. Enter a new name for the autorecoded variable in the New Name field, then click Add New Name. Published with written permission from SPSS Statistics, IBM Corporation. Th… Recoding can be done in one of two ways: In this guide, we will concentrate on recoding into a different variable, for which there are 3 main types of recoding: We will use an example of each type in order to demonstrate how to recode variables in SPSS Statistics. In the Output Variable box, type in a name for the new (grouped) variable. You really should avoid alphanumerics, though, and there is a simple way to make the data better: the Automatic Recode command. Recoding Variables in SPSS. In SPSS, you have two options for collapsing and recoding continuous variables: the IF command and the RECODE command.. 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. We are currently using recode into different variable options because we want to preserve my original data set. 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. You can recode numeric variables into string variables and vice versa. In this example, we will call the new variable MAJORNUM. 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. can be addressed in one RECODE statement, provided that all variables are to be affected in the same way, as in the following example. Defining the variables involves multiple processes and requires careful planning. Next, RECODE usually used for CHI-SQUARE analysis steps to make your continuous data become categorical variables. You can use recoding to produce different values or codes for a variable. In IBM SPSS Statistics, people frequently have categorical variables with lots of values. 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. This tutorial walks you through its main options, best practices and pitfalls. Suppose you have a variable score that you need to collapse into five distinct categories in a new variable grade:. For example, you could collapse salaries into a new variable containing salary-range categories. Keep in mind that you can RECODE and apply value labels to many variables at once. Choose the variable you want to recode and bring it over to the Recode window. 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. Transfer the variable you want to recode by selected it and pressing the button, and give the new variable a name and label. It isn’t unusual for this data to have been entered as string values — alphanumeric characters. Recoding Variables in SPSS Statistics (cont...) Recoding data into two categories. The original value 3 remains unchanged. Suppose we wanted to make a variable called length2 which has lengthsquared. In this section, we will learn Recode into Same or Different variables in SPSS using the Recode function. 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. Recoding Variables in SPSS Statistics (cont...) Recode a given range in SPSS Statistics. 1 Introduction Recoding may be needed in a number of diﬀerent situtions: • To categorise a continuous variable. As demonstrated, a descriptives by category table is a nice way to inspect these results. In SPSS, you can have 2 or more data files open at once (this is better avoided at all times). After recoding we must respecify the value labels for all three variables. 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. Now we will again go to the Transform option and click on Recode into same variable option. Example: The data given below represents a satisfaction rating out of 10 for a new service offered by a company. Published with written permission from SPSS Statistics, IBM Corporation. I'm working with string variables in SPSS and encountered a problem in managing the data. Several variables. The variable length contains the length of the car in inches. 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 means that "under the hood", date-time variables are actually integers! 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. Select the variable that needs to be recoded and enter new values for each response. In this section we will see how to create new variables … Consider the example of a […] All values that are not 1 are left unaltered. EVENT_TIME is in hh.mm..ss format and ranges from 0:0:0 to 23:59:59. Selecting the “Different” function reverses each score and includes them in an extra variable. 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. After recoding we must respecify the value labels for all three variables. Then click on the New Name button. Note that you'll often want to apply or adjust some value labels after recoding. This is a tutorial on how to use the Recode into Same or Different Variables function in SPSS/PASW. Second, the new variables are appended to the end of the active dataset. Do not forget to remember the Change button if not recode your command will fail. Select the string variable of interest in the left column and move it to the right column. formats work_1 to work_8 (pct8). That depends on what metric the original variables are in. Rather than using the recode command, use an if statement like this: SPSS Inc. was acquired by IBM in October, 2009. string c1 to c4 (a7). This procedure will divide your sample into groups (e.g. I wish to create a categorical variable which represents the 3 shifts in which the events occurred. After cloning, we can safely recode into the same variables, leaving the variable order intact and minimizing the need for dictionary modifications after recoding.
