Are you saying that in your new variable, it shouldn't overwrite if there's already a value there? What would the outcome look like for this example? changeVarLabels: Change the variable label. Recoding several variables into several new variables is straightforward: simply fill in multiple input variable names after RECODE and multiple output variable names after INTO. All the traditional mathematical operators (i.e., +, -, /, (, ), and *) work in R in the way that you would expect when performing math on variables. I selected age here which is a numeric variable.After that in the output variable box, write the name of the variable to be formed after recoding. a variable is cut into a smaller number of groups, where each group has the same value range.group_labels() creates the related value labels. In addition to recoding the values of a categorical variable, formats are useful because they enable you to merge or combine categories by defining a many-to-one mapping. What is the advantage of using SPSS over calculating statistics by hand? Example 2: Recoding continuous variables into categories. Is it possible, if more than one choice is indicated , for the Problem. newval specifies the new values to replace oldvalues. STRING declares the variable STATE1 so that it can be used as a target variable on RECODE. Recode multiple response variables in SPSS into a single variable , How to recode multiple response variables in SPSS into a single categorical variable. Th… This creates a dichotomous variable with cut-off point between 2 and 3. Suppose we wanted to make a variable called length2 which has lengthsquared. Sometimes the answers to multiple responses are put into one string variable. There are two common techniques used to accomplish this goal -- recode and compute. The crosstab above shows that 21% of the domestic cars fall into the high mileage category, while 55% of the foreign cars fit into this category. SPSS: Frequency table of multiple variables with same values Below are the steps to generate a frequency table of multiple variables that have the same values. 63 Or it could look like the following: spkg2 1. Ask Question Asked 4 years, 11 months ago. Recode is used to change the values of one variable into other values. Similarly, the following code computes a proportion for each observation: q2a_1 / (q2… Actually not sure you need to do this. Selecting the “Different” function reverses each score and includes them in an extra variable. changeVarNames: Change Variable Names. – thc Apr 11 '17 at 1:19 Yh I … In a lot of data sets people want to recode their continuous scores into categories. Recoding Two Categorical Variables into One. STRING STATE1 (A2). 2 Put the variable you want to recode in the Input Variable → Output Variable box. ... Should I use one stats test or use multiple analysis of variance. 3. bunch recoding of variables in the tidyverse (functional / meta-programing) 1. Note that the variable name can not have space, so I wrote "aggrp". You can use recoding to produce different values or codes for a variable. This changes all occurrences of value 4 to value 3. Multiple sets of value specifications are permitted. Note that you can shorten the comman… Recoding into the same variables works in the same way as recoding into different variables except there’s one important distinguishing characteristic. Only one recoded value per set is allowed to the right of the equals sign. ... SPSS recoding variables data from multiple variables into boolean variables. 1 Choose Transform, Recode, Into Different Variables. A very simple example would be RECODE A (1 = 0) (2=1). A Variables in Set: The variables from the dataset that compose the multiple response set. changeValLabels: Change value labels. First, we make a copy of mpg, calling it mpg3a. Let’s use the auto data for our examples. Re: Recode multiple categorial variables into one variable Posted 08-21-2018 (646 views) | In reply to TraceC It is not clear if you want a separate result if you have only 1 variable with the value of 2 or multiple variables with the value of 2 or what to do with your 'no' or 'unsure' at all. The original value 3 remains unchanged. I am running into a problem, however. A detailed instruction with screenshots can be downloaded here for version 23 or older , or here for version 24 , … It is commonly used to change a string variable into a numeric, nominal equivalent. To use recode, you must provide a list of variables to be recoded and the rules associated with that change. In order to split the file, SPSS requires that the data be sorted with respect to the splitting variable. ... A table summarizing the frequencies of data for one variable b) A spreadsheet into which data can be entered c) A dialog box that allows you to choose a statistical test d) A screen in which ... What does the operation "Recode Into Different Variables" do to the data? To recode variables in Stata, use the recode command. 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. 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. To define a multiple response set through the dialog windows, click Analyze > Multiple Response > Define Variable Sets. applyLookup_expandVar: Recode via lookup table into multiple variables. For surveys, this is typically the set of columns corresponding to the "selectable" choices for a single survey question. 5 4. 521 3. 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. 16 2. In almost every situation, you want to use Into Different Variables. For example, if you are grouping BMI you might use the name ’BMIgroup’. RECODE famimpor (1=4) (2=3) (3=2) (4=1). RECODE famimpor (1,2 =1) (3,4 = 2). 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. For a complete example -with test data- see SPSS - Recode Multiple Variables into One Variable Example. The variable length contains the length of the car in inches. Automatic Recode. Sometimes a variable needs to be changed before it can be used by SPSS. applyNumCheck: Apply recodes according to a numerical check data.frame. In the Output Variable box, type in a name for the new (grouped) variable. Recode variables into equal-ranged groups. With group_var(), variables can be grouped into equal ranged categories, i.e. Recoding Into Same Variables replaces the values in the existing variable. 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. I am seeking help on different approaches to analyzing multiple response variables (I have a dataset from a survey with many questions with responses that are checkboxes ("Check all that apply"). Select the variable that needs to be recoded and enter new values for each response. Recoding can be done in one of two ways: Recoding into the same variable; Recoding into a different variable; In this guide, we will concentrate on recoding into a different variable, for which there are 3 main types of recoding: Recode single values; Recode a given range of values; Recode data into two categories; We will use an example of each type in order to demonstrate how to recode variables in SPSS … R others 2. Assume we have variable famimpor with values 1, 2, 3 and 4, measuring how important having a family is for the respondent. There is an easier way to recode mpg to three categories using generate and recode. For example, to add two numeric variables called q2a_1 and q2b_1, select Insert > New R > Numeric Variable (top of the screen), paste in the code q2a_1 + q2b_1, and click CALCULATE. 4. When you create a question, a Recode Value and a Variable Name are automatically assigned to each answer choice. Each set must be enclosed in parentheses and can result in only one new value. SPSS offers two choices under the recode command: Into Same Variable and Into Different Variables. Recoding variables using recode. Usually, people code single variable with multiple responses and than recode it into several dummy-variables (0,1). To recode multiple variables using the same set of value specifications, specify a variable list before the value specifications. About Recode Values. For a variable (for example, q1) that contains integers ranging from 1 to 7, to collapse the values into three categories, use: recode q1 1=1 2=1 3/5=2 6=3 7=3 changeSPSSformat: Change SPSS format. That will create a numeric variable that, for each observation, contains the sum values of the two variables. Now, you can't recode multiple variables into one with RECODE. 3 5. Using Keyword COPY With Target Variables. Active 4 years, 11 months ago. If you need a regression, for example, you can include all variants except one, and there you go - you know what I mean. Below we see summary statistics for length. SPSS users often want to know how they can combine variables together. Hi SPSS listers, I want to recode seven variables into one variable. In this video Jarlath Quinn demonstrates how to use the compute procedure to calculate the mean of a number of variables to create one combined variable, and also how to use the count values procedure to count how many times a particular value occurs across a series of variables in order to create an overall count. Recode multiple response variables in spss into a single variable. changeMissings: Change missing code. Just make sure that the number of input variables matches the number of output variables. Sample dataset attached. RECODE famimpor (4=3). Or we might want to make loglen which is the natural log of length. This note demonstrates the use of Multiple Responses Analysis in analyzing multiple responses data using SPSS software. 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. RECODE STATE ('IO'='IA') (ELSE=COPY) INTO STATE1. As a first approach, I am using PROC TABULATE and trying to follow these instructions. Let's use the compute command to make a new variable that has the length in feet instead of inches, called lenft. In this section we will see how to create new variables with compute. I want to turn the seven variables into one variable, with 1=Native American, 2=Asian, 3=African American, and so on. RECODE specifies STATE as the source variable and STATE1 as the target variable. Commonly, this is the concatenation of the codes of possible (positive) answers. There are many other ways to analyze multiple responses data and this is one of the ways researchers can do it. For our example data, such a variable could look like the following (using numeric codes): spkg1 1. Dichotomize Multiple Variables into New Variables. SPSS will not stop you from using a continuous variable as a splitting variable, but it is a bad idea to try to attempt this; SPSS will see each unique numeric value as a distinct category. For example, the following character format recodes values of the TYPE variable and also combines the 'SUV' and 'Wagon' categories into a single category. For example, we may want to classify people, based on their 0-100% test scores into one of three groups, Pass, Resit and Fail. (If you have value labels, perhaps you should change these now accordingly). All other values remain unchanged, too. Let me know if anyone can help ... As a result, the values for this variable are either [empty], 0 or 1. The original value IO is recoded to IA. Select the desired variable and move it to the right box as shown in the picture.
