Remember that each individual's results go on a separate line (row) in SPSS Statistics. Double-clicking on a function name will add it to the "Include if case satisfies condition" box. Visit the IBM Support Forum, Modified date: Cite. To specify such conditions, click If to bring up the Recode into Different Variables: If Cases window. Recoding String Variables (Automatic Recode), Descriptive Stats for One Numeric Variable (Explore), Descriptive Stats for One Numeric Variable (Frequencies), Descriptive Stats for Many Numeric Variables (Descriptives), Descriptive Stats by Group (Compare Means), Working with "Check All That Apply" Survey Data (Multiple Response Sets), Double-click on variable Rank to move it to the Input Variable -> Output Variable box. How to recode multiple response variables in SPSS into a single categorical variable. RECODE famimpor (4=3). 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? This method tells SPSS exactly how to map each old category onto a new category. No results were found for your search query. Imagine a number line: In that instance, the score 69.99 would fall into a "gap" not covered by any recoding rules. NOTE: This syntax has been tested in SPSS Version 22 and 23. In general, your instructions to SPSS should be specified in such a way that all possible outcomes are accounted for, regardless of whether you're using the menus or syntax. Click in the menubar on 2. This will allow you to specify the conditions under which the recode will be applied to your data. 4Output variables are strings and Convert numeric strings to numbers: These options change the variable type of the new variable. In particular, a question in a survey may receive zero or more positive answers depending on the characteristics or behavior of the respondent. The COMPUTE statements are where the new variable(s) are actually computed or set. When entering a question that has multiple answers allowed into SPSS, you need to split each option into a separate variable. 2. For example, the response to a particular question may have been measured on a 5-point scale and you might want to reverse the coding so that 1 becomes 5, and so on. IF v#g=1 ethnic=7. That is, the changes do not overwrite the original variable; they are instead applied to a copy of the original variable under a new name. Or you could just enter the codes into the SPSS dataset directly (e.g. 1. For the "D" and "C" grades, we could try specifying the ranges as [60, 69.9] -> D and [70, 70.9] -> C. This could work if scores were only recorded to one decimal place, but what would happen to a score with two decimal places -- say, 69.99? Note that if you want to set a a variable equal to a missing value in a COMPUTE statement, use the syntax var=$SYSMIS. Move the $Fruit variable into the Table (s) For area, as shown. 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). Recode into Different Variables and DO IF syntax create a new variable without modifying the original variable, while Recode into Same Variables will permanently overwrite the original variable. SPSS has a two-step process to use multiple response sets using the dialog windows: Define the multiple response set. Suppose we want to recode these scores to have a letter grade using the scheme described above. B Output Variable: Define the name and label for your recoded variable(s) by typing them in the text fields. These conditions are statements (or chains of statements) that evaluate as true or false. You may have to record the respondent ID number in a spreadsheet along with your numeric recode. If missing value conditions are used in ELSE IF statements, they are ignored. We will show three different ways of defining the categories that produce identical results. 2 Categorising a continuous variable 1 Choose Transform, Recode, Into Different Variables. SPSS: Multiple response tables (via Custom tables) (by P. Stikker) Creating a multiple response set In order to create a frequency table or a cross table from a question with multiple answers, you first need to create a multiple response set. To recode into different variables, click Transform > Recode into Different Variables. The term $SYSMIS refers to system-missing values. The same is true for creating hirt1 from trialr1. Multiple responses—in the sense used here—are defined by a degree of open-endedness. That is, the original values will be replaced by the recoded values. The above example showed how to discretize a continuous variable into three categories using Recode into Different Variables. ELSE is optional -- you don't necessarily have to use it, but it is often more convenient to use than addressing every possible outcome using ELSE IF. 16 April 2020, [{"Product":{"code":"SSLVMB","label":"SPSS Statistics"},"Business Unit":{"code":"BU053","label":"Cloud & Data Platform"},"Component":"Not Applicable","Platform":[{"code":"PF025","label":"Platform Independent"}],"Version":"Not Applicable","Edition":"","Line of Business":{"code":"LOB10","label":"Data and AI"}}], Recode multiple response variables in SPSS into a single variable with priority. Multiple responses depend on the half normal percent probability and the ANOVA. © 2021 Kent State University All rights reserved. Suppose we have test scores as percentages, and want to convert those percentages to a letter grade. This computation must be done using syntax. The original value 3 remains unchanged. Assume we have variable famimpor with values 1, 2, 3 and 4, measuring how important having a family is for the respondent. To create a frequency table or a cross table from these variables, you can let SPSS know that these belonged to each other by creating a multiple response set. There are many kinds of conditions you can specify by selecting a variable (or multiple variables) from the left column, moving them to the center text field, and using the blue buttons to specify values (e.g., “1”) and operations (e.g., +, *, /). Once you click Old and New Values, a new window where you will specify how to transform the values will appear. In general, it is good practice not to recode into the same variable because it overwrites the original variable. DO IF-ELSE IF syntax performs similarly to the Recode procedures, but allows for more control over specifying numeric ranges. The "Lowest thru" option acts as "less than or equal to some-number", and the "thru Highest" option acts as "greater than or equal to some-number". Recoding Variables - SPSS Tutorials, This tutorial shows how to compute new variables in SPSS using formulas and A Target Variable: The name of the new variable that will be created a variable (or multiple variables) from the left column, moving them to the Statistics Software Spss. In the counted value, put the value for "yes". In the name, write the name of heading for these responses (without spaces). Choose Analyze→Multiple Response→Frequencies. I am strugling recoding missing values in SPSS using the graphical user interface. Need more help? RECODE famimpor (1,2 =1) (3,4 = 2). D If: The If option allows you to specify the conditions under which your recode will be applied. You will use one or more variables to define the conditions under which your recode should be applied to the data. Syntax to read the CSV-format sample data and set variable labels and formats/value labels. Please try again later or use one of the other support options on this page. Dichotomize Multiple Variables SPSS Recode Example 2. However, if we wanted to discretize into four or more categories, Recode into Different Variables isn't equipped to properly define each range. 1 0 0 0 0 1 2. Double-click on variable Rank to move it to the Input Variable -> Output Variable box. When recoding variables, always handle the missing values first! C Old and New Variables: Click the Old and New Values to specify how you wish to recode the values for the selected variable. We should also be able to check our new variable to make sure that it performed as we expected. When you are ready to run the procedure, click OK. Now your new variable will be recoded according to the criteria you specified. This tutorial shows how to use Recode into Different Variables and DO IF syntax to change or merge the categories of string or numeric variables in SPSS. Note that this method works OK for integers, but will often yield unexpected results when used on variables that have one or more nonzero decimal places. This note demonstrates the use of Multiple Responses Analysis in analyzing multiple responses data using SPSS software. Answer. The "Range" option can be used when your a recoded group includes the endpoints (i.e., is defined by "greater than or equal to" AND "less than or equal to" statements). Exampe of data: 2 The default specification for a recode is to Include all cases. Enter the data in the SPSS Statistics Data Editor and name the variable " Runs ". In the Output Variable area, give the new variable the name, Handle missing values first: In the Old Value area click, Define the underclassmen group (1): In the Old Value area click, Define the upperclassmen group (2): In the Old Value area click, 2 = Commute is more than 30 minutes, but less than 60 minutes (30 < time < 60), Double-click on variable CommuteTime to move it to the Input Variable -> Output Variable box. Once again, suppose you wanted to create a dummy variable from trial1 with a cutpoint of 2. You may encounter this syntax error after executing a DO IF block: If this happens, you may need to add a hyphen (-) before the COMPUTE statement(s). 1 1 0 0 0 0 0 0 0 3 The center of the window includes a collection of arithmetic operators, Boolean operators, and numeric characters, which you can use to specify the conditions under which your recode will be applied to the data. When using DO IF, any conditions based on missing values must be included in the DO IF step; they can not be included in ELSE IF statements. Syntax to add variable labels, value labels, set variable types, and compute several recoded variables used in later tutorials. To set priorities, you just change the order of the IF statements. This is especially true if using the "Lowest thru", "thru Highest", or "Range - through" options. IF v#c=1 ethnic=3. IF v#b=1 ethnic=2. If the new variable appeared but all of the values are missing, then there is something wrong with your code; you may have forgotten an EXECUTE statement. You can find your new variable in the last column in Data View or in the last row of Variable View. 2 1 1 0 0 0 0 0 0 The Multiple Response Frequencies dialog box. For example, for case 2 in the example data, both v#a and v#b are selected. Let's use Recode into Different Variables to merge the categories and create a new indicator variable called RankIndicator with the levels Underclassman (1) and Upperclassman (2). Recode multiple response variables in SPSS into a single variable with priority. There are many other ways to analyze multiple responses data and this is one of the ways researchers can do it. The multiple response sets that are defined through Analyze - Multiple Response - Define Variable Sets only exist for as long as that current session of IBM SPSS Statistics is open. If you do use ELSE, it must be at the very end of the loop (right before the END DO statement). RECODE famimpor (1=4) (2=3) (3=2) (4=1). Using "All other values" to define group 2 was completely dependent on us correctly accounting for all other possible categories first, including the missing values. If you want to discretize a numeric variable into more than three categories, or if you want to perform a recoding based on more than one variable, you'll need to use DO IF-ELSE IF syntax. A basic introduction on how to deal with multiple response data sets using SPSS Class ranks for high schools and colleges are are nicknames for what year of study the person is completing: "freshman" (first-year), "sophomore" (second-year), "junior" (third-year), "senior" (fourth-year). Recode into Different Variables was able to correctly account for all possible values in that situation. The left column lists all of the variables in your dataset. Example: 2New Value: Specify the new value for your variable (i.e., a specific numeric code such as “2,” system-missing, or copy old values). (Note that although SPSS indicates numeric missing values using period characters (. Setting up multiple responses set Now we want to group together Q1c-Q1f so that SPSS knows that it is actually a question with multiple responses. You only have to use one of these; we show multiple methods to show that there is flexibility in how you define the groups. Click on (or in SPSS 23 on ) 3. Click the arrow in the center to move the selected variable to the center text box, (B). After recoding we must respecify the value labels for all three variables. SPSS also provides extensive data management functions, along with a complex and powerful programming language.
