Step 1. I am analyzing some student survey data which had a âraceâ variable where respondents had the option to select more than one race category. Both variable should be either strongly agree or agree. Finally, we'll inspect if the result is correct by running CROSSTABS.eval(ez_write_tag([[468,60],'spss_tutorials_com-box-4','ezslot_0',108,'0','0'])); Note that every table row contains only zeroes except for one cell. Merging some categories of a categorical variable in SPSS is not hard if you do it the right way. Now I want to make out of these 4 variables (V1-V4) one categorical variable (let's call it V5 "used rooms") with the values 1 = kitchen, 2 = WC, 3 = living room and 4 = hallway. COMPUTE FILT_1 = 0. IF v#g=1 ethnic=7. An example of such a value label is COMPUTE inc_3 = 0. I want to select the cases which have given specific ranks (eg: Strongly agree and agree) to two variables. Keep in mind that this new variable doesn't come with any variable labels or value labels. We'll now show two solid approaches for doing just that. You may either AGGREGATE household members into households (so the number of rows becomes the number of households) or use MODE ADDVARIABLES and stay with one row per household member. However, since these don't show up in any way, this does not bother us either. See below: COMPUTE RACE_ETH = 0. How can I do it in SPSS? We'll therefore propose a faster approach that circumvents this. Next, we'll point out how it how to easily use it on other data files. In the SPSS menu, select Analyze>Compare Means>One Sample T-test Select the variable(s) from the list you want to look at and click the button to move it into the âTest Variable(s)â area. EXE. IF(sum(inc_1 to inc_2) > 0) inc_3 = 1. Because you are creating a new variable rather than editing an existing variable, the variable has an automatically generated name such as NewVar. doctor_rating = 3 (Neutral) nurse_rating = . 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. Open the file in SPSS and have a look at it. You may follow along by downloading and opening hospital.sav. This tutorial demonstrates just that. Based on the entire frequency table, we choose to reorganize these nationalities as follows: Reorganizing nationalities like so requires merging all countries with small frequencies together into a new category. The result is shown in the screenshot below. The United States Census Bureau has a long history of conducting research to improve questions and data on race and ethnicity. Please advice. IF v#e=1 ethnic=5. It is assumed that all values in the original variables consist of. IF (RACE = 1 AND HISPANIC = 0) RACE_ETH = 1. However, the real information is usually in the value labels instead of the values. document.getElementById("comment").setAttribute( "id", "adb3c7940b3b846be183d8ff7da6bf59" );document.getElementById("de7f0aa44f").setAttribute( "id", "comment" ); I see. doctor_rating = 3 (Neutral) nurse_rating = 7 (System missing). One approach would be to use SPSS syntax editor. Case Numbers ⢠Each case in an SPSS file should include a case number. 2. I am still relatively new to SPSS. SPSS is easy to learn and enables teachers as well as students to easily derive results with the help of a ⦠The result is shown in the screenshot below. There are 32 columns (variables) and 400 rows (cases). However, for reporting purposes we usually display only value labels and not the underlying values. Merging some categories of a categorical variable in SPSS is not hard if you do it the right way. Since the first census in 1790, the Census Bureau has collected information on race/ethnicity and the census form has reflected changes in society and shifts that have occurred in the way the Census Bureau classifies race and ethnicity. Many easy options have been proposed for combining the values of categorical variables in SPSS. You can do so by AGGREGATE. This is the name of the variable you are creating by adding two or more other variables ⦠Say race has three values, 1 2 and 3, and you want to make three dummies, race1 race2 and race3.Note that this does not work for string variables (but you can first convert the string variable to numeric and then use this procedure).. DATA LIST FREE / race⦠⢠The order of variables in the SPSS data file normally should be the same as the order of items in the questionnaire. Since this pattern holds for all rows, we conclude that the result is indeed correct. ⢠Use variable names that help you identify the scale or instrument to which they apply. After creating the new variables, they are entered into the regression (the original variable is not entered), so we would enter x1 x2 and x3 instead of entering race into our regression equation and the regression output will include coefficients for each of these variables. We'll walk through them below. Further, note that the syntax we used made a couple of assumptions. IF v#h=1 ethnic=8. From the menu, choose. I have a rather urgent question. Then enter the test value. This will, however, require SPSS version 14 or higher with the SPSS Python Essentials properly installed. IF (RACE = 2 AND HISPANIC = 0) RACE_ETH = 2. After doing so, we can use the syntax below for merging our categories as desired. 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. (). Uninsured Example ***Confidence Intervals are close to what you get in SUDAAN, but SUDAAN is still the Note that all variables are numericwith proper value labels applied to them. In order to split the file, SPSS requires that the data be sorted with respect to the splitting variable. As it stands, Qualtrics creates a variable for each possible choice, assigning a "1" if a respondent selected it and a "." IMPORTANT NOTE. Sometimes you will want to transform a variable by combining some of its categories or values together. You now need to define what information will be displayed on the X-axis and the Y-axis of the graph. Create a new variable, p.race. These categories are: 1. American Indian/Alaskan Native 4. (). That is, we're using 1, 2, 11, 12 (...) instead of 1, 2, 3, 4. This gives you a blank histogram template. so that you can analyse them statistically. * the combination must be the last in the sequence. First, ⦠Do you have an idea on how to solve that? Click on the link entitled Fast-food study SPSS data. For estimates by age and race and Hispanic origin, use of the following age categories is recommended for reducing the variability in the sample weights and therefore reducing the variance of the estimates: 5 years and under, 6-11 years, 12-19 years, 20-39 years, 40-59 years, 60 years and over. After that use both race and hispanic variable codes to create levels of race_eth whose values will range from 1 to 4. In this case, you want each bar of the histogram to represent a score on the The syntax below shows how to do so. Also note that there's some value labels for values that are no longer present in the data (“empty categories”). over sets of rows (members in single household)? m.out=matchit(ESRD~Age+Sex1+Race,method="nearest",data=datamatch,ratio=5) the above syntax gives me exact matching for age (I think). I'm trying to combine a set of "select-all-that-apply" variables into one variable from a dataset downloaded from Qualtrics. Before doing so, however, we'll first apply a variable label to this variable.eval(ez_write_tag([[468,60],'spss_tutorials_com-medrectangle-3','ezslot_3',133,'0','0'])); The frequency table tells us that we have 100 respondents from Belgium and 201 from England but only 2 from France and 1 from Germany. doctor_rating = 3 (Neutral) nurse_rating = 7 (System missing). To replace this, simply click on the box containing the variable and drag it back to the Variables list. Now say we'd like to combine âdoctor_ratingâ and ânurse_ratingâ (near the end of the file). Right, we first download and install the SPSS Clone Variables Tool. Type the name of your new variable in the space under "Target Variable." We recommend you try the examples for yourself by downloading and opening hotel_evaluation.sav. Your comment will show up after approval from a moderator. Create a variable called race_eth then assign a value of 0. Specify an old value and a new value. Ethnicity variable. This becomes apparent when running FREQUENCIES (syntax below, step 3). In my survey I asked the respondents to check the boxes that apply to how to describe their ethnicity. So that every "1" in one variable is a category in the new variable V5. A nicer result can be obtained without changing the basic syntax for combining categorical variables. Hello, I am inexperienced in SAS and need some help. in SPSS each category is split into its own variable. Now say we'd like to combine âdoctor_ratingâ and ânurse_ratingâ (near the end of the file). RECODE inc_3 (2 THRU HI = 1). Clicking on the cell for the relevant variable will summon a pop-up menu like the one shown below. If you let the cursor hover over a variable name, you will get a longer description of what it's about; most of these are self-explanatory. In the Variables pane, use Shift+click or Ctrl+click to select the variables that you want to merge. Assign p.race the value of one of the eight variables for race/ethnicity (below). Right, when doing a routine inspection of this data file, we'll see that the variable nation has many small categories. Black 3. IF minority_dummy=1 race=3. White 2. For example, you may want to change a continuous variable into an ordinal categorical variable, or you may want to merge the categories of a nominal variable. For example. Later, I want to use this binary variable as a dependent variable in a logistic regression model. Because of that I have 6 separate race variables. document.getElementById("comment").setAttribute( "id", "ac413c3a1dcd8b1a3761dc5e9e79557c" );document.getElementById("d7c2cba526").setAttribute( "id", "comment" ); *Required field. FREQ ALL. In this example, weâre testing the hypothesis that the median house value is 200,000. Each case in the one file corresponds to one case in the other file. IF white=1 race=1. Finally, we inspect the result in the same way as we did previously.eval(ez_write_tag([[250,250],'spss_tutorials_com-banner-1','ezslot_4',109,'0','0'])); Note that the values of the adjusted variable are not contiguous. 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. In SPSS, this type of transform is called recoding. I have tried so many things to no avail. Enter an output (new) variable name for each new variable and click Change. If you select multiple variables, they must be the same type (numeric or string). We recommend you try the examples for yourself by downloading and opening hotel_evaluation.sav. Note that we are able to set the variables equal to zero first, without worrying about missing cases only because there happen to be no missing cases for the race variable. IF v#c=1 ethnic=3. Right, when doing a routine inspection of this data file, we'll see that the variable nation has many small categories. (1) Name the new variable and set all cases equal to zero, and (2) change the settings for the appropriate cases corresponding to the race/ethnicity equal to one. Like so, we can quickly confirm that all 100 respondents from Belgium (first row) still have “Belgium” on our new variable. Result: inc_3 will be 0 or 1 if the sum of inc_1 and inc_2 is greater than zero. Continuous versus categorical variables: In both files each case has an identifier, and the identifiers match across cases. Use either SELECT IF (delete cases) or FILTER (filter out cases). We'll therefore apply these ourselves. ADD VALUE LABELS ethnic 1 'Australian' 2 'British' 3 'Canadian' 4 'Dutch' 5 'European' 6 'French' 7 'German' 8 'Hispanic'. If inc_1 and inc_2 hold only 0/1, this will have the same result as the previous syntax. For example you will need to assign numeric values for gender (0 = boys, 1 = girls) and ethnicity (0 = White British, 1 = Mixed Heritage, 2 = Indian, etc.) Before doing so, however, we'll first apply a variable labelto this variable. Your comment will show up after approval from a moderator. set have; format RaceAndEthnicity $ 20.; If Ethnicity= "1" then RaceAndEthnicity = "Hispanic - Any Race"; Else If Ethnicity= "2" and Race = "White" then RaceAndEthnicity = "White NH"; Else If Ethnicity= "2" and Race = " Black or African American " then RaceAndEthnicity = "Black NH"; You want to count values (maybe 0 = female, 1 = male or something?) IF v#d=1 ethnic=4. Merge-SPSS Merging Data Files In SPSS You have two data files. This becomes apparent when running FREQUENCIES (syntax below, step 3). You may follow along by downloading and opening hospital.sav. IF white = 1 AND minority_dummy = 1 race=2. I want to combine two categorical variables (income from dependent employment and income from independent employment, both coded with yes/no) into one categorical variable, also with the values yes/no. Creating Race/Ethnicity Variable for Race/Ethnicity ... Can sort, summarize, subset, merge, and concatenate data sets, create new variables. We realize that many readers may find this syntax too difficult to rewrite for their own data files. Most real world data will satisy those. Use a value that's not yet present in the original variables and apply a value label to it. We'll call this new variable rec_nation which is short for “recoded nation”. The latter are referred to as “small categories” and we often find these undesirable. EXECUTE. doctor_rating = 3 (Neutral) nurse_rating = . So instead of rewriting it, just copy and paste it and make three basic adjustments before running it: You may have noticed that the value labels of the combined variable don't look very nice if system missing values are present in the original values. 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. After doing so, the resulting value label will look as follows: We first present the syntax that does the trick. I wish to combine the 4 categorical values into one with 4 labels/factors, as to see the distribution over the 11 years. The first option we proposed uses only very basic syntax so it will work fine on all SPSS versions. EXECUTE. Note that this is an SPSS Extension Bundle. I exported Qualitrics data to SPSS. I typically do this kind of stuff with a simple IF command. VALUE LABELS race 1 'white' 2 'white minority' 3 'non-white minority'. How do I combine these into one variable? IF(Q1 > 4 AND Q2 > 4) FILT_1 = 1. You want to match up records by identifiers. for missing if a respondent didn't select it. Note that all variables are numeric with proper value labels applied to them. The NHANES sample weights can be quite variable due to the oversampling of subgroups. SPSS (The Statistical Package for the Social Sciences) software has been developed by IBM and it is widely used to analyse data and make predictions based on specific collections of data. SPSS users often want to know how they can combine variables together. A disadvantage, as we saw, is that it requires applying variable and value labels to the new variable. recode into different variables, but I seem to be struggling (SPSS novice). COMPUTE inc_3 = sum(inc_1 to inc_2). A very decent way to merge our small categories is creating a new variable with RECODE (syntax below, step 1). A detailed instruction with screenshots can be downloaded here for version 23 or older , or here for version 24 , ⦠Click Old and New Values. Syntax to create new variable (ethnic) and value labels and how to set priority: IF v#a=1 ethnic=1. Thanks!
