Almost every SAS programmer has written a DATA step that uses IF-THEN/ELSE logic or the SELECT-WHEN statements to recode variables.Although creating a new variable is effective, it is also inefficient because you have to create a new data set that contains the new variable. Survey data often contains sets of categorical variables that need to be recoded into binary variables. Whereas when you’re using SPSS recode into different variables range can be manipulated with little concern for the loss of data, recoding into the same variables will actually delete your original data. In Minitab, try this: Choose Data > Recode > To Numeric. Click on OK to perform the recode. French / Français Similarly, we might code the dichotomous variable for sex: 0 = Female 1 = Male Dichotomous variables can also be dummy variables.

The above examples illustrate how to recode variables into the same variables. Enable JavaScript use, and try again. Recode into Different Variables: Old and New Values You can define values to recode in this dialog box. To use recode, you must provide a list of variables to be recoded and the rules associated with that change.. 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 3 Using Recode to make a quantitative variable into a set of ordered categories From the Date, Syntax or Output windows… Transform Recode Into Different Variables • recode statements can be used to create new “versions” of variables • the new variable will “appear” in the rightmost column in the data set forvalues i = 1/3 {generate nx‘i’ = 6-x‘i’} In the categorical variable religion, we want to change 1, 3, and the real and integer numbers 3 through 5 into 6; we want to set 2, 8, and 10 to 3 and leave all other values unchanged.. recode religion 1 3/5 … We will illustrate this with the hsb2 data file with a variable … Recoding variables Recoding categorical or quantitative variables can be useful in a number of circumstances. On the Variables and Questions tab, select multiple variables at the same time and recode them together. On the right side of the window, under Output Variable, type a name for the new variable, and optionally a variable label. You can use recoding to produce different values or codes for a variable. You can use recoding to produce different values or codes for a variable. In the previous section, we have learned how to Recode into Different variable options and the advantage of having Recode into different variable options. Chinese Traditional / 繁體中文 Thai / ภาษาไทย First, we omitted the parentheses around the rules. Just make sure that the number of input variables matches the number of output variables. You will now see the “Recode into Different Variables” window. Social research (commercial) 1 Choose Transform, Recode, Into Different Variables. DISQUS’ privacy policy. For example: Market research Change one question and then use Modifying Data - Use a Question as a Template for Modifying Other Questions to change similar questions. Whilst you can also use the Recode into Different Variables procedure to create dummy variables if you have SPSS Statistics version 22 or later, we set out the Create Dummy Variables procedure in this guide because it is dedicated to creating dummy variables and is a lot easier and quicker to use. If you are following along with the NHANES data, the variable is AUAEXSTS. ... We can interpret this as the first five age groups … Currently the mpg (miles per gallon) variable of mtcars is a continuous numeric variable, but it may be more useful if mpg was a categorical variable that immedietly told you if the car had low or high miles per gallon.. We can make categories through indexing variables that meet certain criteria. You will be presented with the pop-up menu shown below, so move the SEC variable into the box marked Numeric Variable -> Output Variable. You can make it clear by creating a data dictionary as a separate file to accompany the dataset. If datasets are in different locations, first you need to import in R as we explained previously. If you’re following along with the NHANES data, the variable is AUXTMEPR. Before we look at this example, though, let us review the syntax of the recode statement. In the recoding scheme, we need to specify how the values of old variables are converted into the values of new variables. The left side of equal signs (=) is for the values of old variables, and the right side for the values of new variables. Japanese / 日本語 In this example, we will illustrate various aspects of how the program works by recoding age into a new variable with four categories. This is not how Displayr works. For example, you might want to convert a continuous reading score that ranges from 0 to 100 into 3 groups (say low, medium and high). In the “Recode into Different Variables: Old and New Values” dialog box, select “Range:” and enter 15 in the first box and 24 in the text box below. Recoding a categorical variable. The left column lists all of the variables in your dataset. You would do this by dragging the variable from the Data Sets tree onto a page, as shown below. We type recode old-variable, and then generate new categories using a set of parentheses for each category. Recoding into the same variables works in the same way as recoding into different variables except there’s one important distinguishing characteristic. This post demonstrates how to create new variables, recode existing variables and label variables and values of variables. Romanian / Română So, IPP should be a new variable including initial variables 1-4 and the INPP should be a second new variable including initial variables … Click Old and New Values and specify how to recode values. Search in IBM Knowledge Center. Recode an existing variable in Stata. Catalan / Català Click on Change. > Can we recode into different variables (SPSS) in order to > create the IPP variable out of the 4 initial variables and the > NIPP variable out of the e remaining initial variables? Standard formats for dates and time. Recoding can be done in one of two ways: Recoding into the same variable This cookbook contains more than 150 recipes to help scientists, engineers, programmers, and data analysts generate high-quality graphs quickly—without having to comb through all the details of R’s graphing systems. 2 Put the variable you want to recode in the Input Variable → Output Variable box. The merging and the values are completely independent (when you merge it does not affect the values and recoding the values has no impact on the merging of categories). (The only time you'd use that is when fixing fouled labels.) SPSS offers two choices under the recode command: Into Same Variable and Into Different Variables. Dutch / Nederlands Here we use the -generate- command to create a new variable representing population younger than 18 years old. We still do not have labels attached to the values of the new variable. ), so we strongly recommend specifying generate(). By commenting, you are accepting the Click the arrow in the center to move the selected variable to the center text box, (B).
