# spss compute multiple variables at once

In order to split the file, SPSS requires that the data be sorted with respect to the splitting variable. You define it based on the variables you’ve already defined, but it doesn’t show up on the SPSS Variable View tab. We'll basically . RE: Compute Variable Choice Not There (SPSS 27) By: Jon Peck , 17 hours ago I don't know why the Compute dialog would disappear, but Big Sur does require the fixpack for V27. 2. This looks strange; it works because the multiple SELECT IF statements it generates, 'and' together. Daten zur Vorbereitung von statistischen Analysen grafisch darstellen (deskriptive Statistik) 7. That is, when computing the denominator, R sums the values of every observation in the data set. It is possible to have three-way interactions or more, but we focus on the two-way case for ease of explanation. Multiple Variables. However, readers who struggle their way through will learn a very efficient solution that works for many other situations too. Multinomial logistic regression: This is similar to doing ordered logistic regression, except that it is assumed that there is no order to the categories of the outcome variable (i.e., the categories are nominal). Fälle/ Variable auswählen 5. ("MAX" and "MIN" work for string variables.) show format. Daten auf Eingabefehler kontrollieren 3. One-way ANOVA in SPSS Statistics Introduction. How to Combine Two or More Categorical Variables into One in SPSS Showing 1-110 of 110 messages. In the ‘Numeric Expression‘ box, enter the function ‘MEAN()‘. SPSS: Frequency table of multiple variables with same values. How to Concatenate? COMPUTE #TAKE_IT = 1. 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. Merging two or more sting variables into a single variable is called concatenating variables This function can be very useful if you are working with string data in SPSS One common use of this function is to bring first name and last name from two variables into one single full name variable 2 . The issue is not necessarily of SPSS, rather how the weighting is used. For this example let’s create a new variable which combines the two existing questions in the LSYPE dataset: 1) Whether or not the parent wants their child to go to full-time education after the age of 16 (the variable named parasp in SPSS, 0 = no; 1= yes). You can merge two or more variables to form a new variable. This is suﬃciently greater than 0 … Kennzahlen zur Vorbereitung statistischer Analysen berechnen 6. In SPSS, new numeric variables initially have an f format, usually F8.2. This tells R to divide the value of q2_a1 by the sum of all the values that all observations take for this variable. Another is a DO REPEAT construct. This tutorial will show you how to use SPSS version 12 to perform a one-way, between- subjects analysis of variance and related post-hoc tests. I have a data base of patients which contain multiple variables as yes=1, no=0. If there is only one target variable list, you can double-click individual variables to move them from the source list to the target list. This isn’t a bad thing to do if you only have one predictor variable (from the logistic model), and it is continuous. > second one "non-Institutionalized Political Trust" (NIPP). Dabei entstehen mehrere (z.B. SPSS users often want to know how they can combine variables together. This is called a two-way interaction. In the new Compute Variable window, first enter the name of the new variable to be created in the ‘Target Variable‘ box.. Solution 2: Copy String Variables Before Conversion. We use the Compute function to create totally new variables. So, I have a data base of patients which contain multiple variables as yes=1, no=0. @James Stanley makes an important point. 2 An Example in SPSS: Attitude Towards Immigration, Conformity Values, and Voting. This may or may not be the same as the products of the weight variables (most likely not). DELETE VARIABLES. The screenshot below shows an example SPSS dataset I created for demonstration purposes (as you can see at the bottom of the screenshot, we are seeing the "variable view", as opposed to "data view". COMPUTE varnew = MEAN.2 (var17, var18, var19, var20). newval specifies the new values to replace oldvalues. For example, using the hsb2 data file we will predict writing score from gender ( female ), reading, math, science and social studies ( socst ) scores. Hi, I am new on SPSS, I hope you can provide some insights on the following. I did not find an answer online, but I did … fünf) vervollständigte Datensätze, um die Unsicherheit bzgl. It occurs quite frequently that you may wish to get rid of some variables in the data set. Hi, I am new on SPSS, I hope you can provide some insights on the following. 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. Below are the steps to generate a frequency table of multiple variables that have the same values. Home- SPSS tables overview (this site uses frames, if you do not see the weblecture and definitions frames on the right you can click here) 2.6.1.3. Using SPSS for One Way Analysis of Variance. That is, hazard ratios change across time; the values of one (or more) of your covariates are different at different time points. Warning: The problem here described is even more pertinent if you want to compute indices by adding several variables with the help of the SUM( ) operator. > > 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? Basically just making one variable (0= LGBT, 1 = not LGBT) , how do i combine the data from both gender & sexuality? Daten transformieren/ neue Variabeln erzeugen/ Daten aggregieren oder verschmelzen 4. I wonder if it is possible not only to combine different variables into one variable via "compute" or "transform" in SPSS but to add subcategories to that variable too. This may be either because you wish to analyze only some of the variables or because you have created some intermittent variables which are not needed any longer. Below I give examples of using TO and defining a set of variables via a macro. Compute Time-Dependent Covariate . The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups). How to Combine Two or More Categorical Variables into One in SPSS: southernpsy: 5/29/09 11:08 AM : I am an SPSS novice, and I found this group recently when I was trying to determine how to combine two categorical into one variable in SPSS. This example will focus on interactions between one pair of variables that are categorical and continuous in nature. One way to rectify this problem would be to: Click in the field under "Label" for each variable and simply type in a label. Computing variables. Then one has to identify the weights for each of the categories (i.e., sub populations/strata) identified by the new variable. Recode changes to codes of one or more variables (varlist1) according to a list of specifications enclosed in parentheses. There are certain situations in which you would want to compute a Cox Regression model but the proportional hazards assumption does not hold. This is useful when you want to create a total awareness variable or when you want two or more categorical variables to be treated as one variable in your tables. Area2, and Area3. Add Variables merges the active dataset with another open dataset or external IBM® SPSS® Statistics data file that contains the same cases (rows) but different variables (columns). When merging categorical variables, the new variable will automatically have the same categories as the categorical variables you are merging. You might get small values for some cases simply because they have missing values. One trick (thanks, Jan Spousta) is SELECT IF MAX(VAR1 TO VARn) EQ "testval" AND MIN(VAR1 TO VARn) EQ "testval". Variable View SPSS No Variable/Value Labels. When more than one dependent variable is analyzed, then it is necessary to ask, “how highly are the dependent variables correlated?” In the present case, the correlation between mRNA values in the three area is around 0.50. It doesn’t even show up when you list your data on the Data View tab. I have one variable to determine if someone is trans (0= yes, 1= no) and another variable for sexuality (0 = straight , 1 = bi , 2 = gay) what I want is to compute an LGBT variable. There are also multiple response sets, and defining macro calls to a specific set of variables. Those who really want to know can confirm this by running. One of the great strengths of using R is that you can use vector arithmetic. Consider the expression q2a_1 / sum(q2a_1). Formats can be set for multiple variables at once; after FORMATS, specify one or more variable names followed by their format. But it does show up among the items you can choose from when defining graphs and tables. Things now become a bit more technical. A good example is to add the suffix ‘_avg‘ to the variable name to signify that it is a mean. copy all string variables; convert all string variables; compare the original to the converted variables. Multiple Imputation Diese seit SPSS Statistics 17 verfügbare Prozedur, deren Leistungen auch über den Menübefehl Analysieren > Multiple Imputation abrufbar sind, unterstützt neben einer Analyse der aufge-tretenen Muster fehlender Werte die multiple Imputation. Remember, SPSS does not like spaces in the variable names. Multiple regression is very similar to simple regression, except that in multiple regression you have more than one predictor variable in the equation. You can also select multiple variables: To select multiple variables that are grouped together in the variable list, click the first variable and then Shift-click the last variable in the group. 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, you might want to merge a data file that contains pre-test results with one that contains post-test results. Typische Arbeitsschritte in SPSS 1. Variablen definieren 2.
