Using Compute Variable or Count Values within Cases to Create Index Variables for a group of Variables with the same property SPSS INDEX Function By Ruben Geert van den Berg under String Variables. The SPSS INDEX function returns the position of the first occurrence of a given expression within a string. If the expression does not occur in the string, it returns a zero. As a rule of thumb, always use it as CHAR.INDEX. The reason for this is explained SPSS Unicode Mode. Note that string values are case sensitive

- - Using the menu: select TRANSFORM> COMPUTE then enter id in the Target Variable text box and $ casenum in the Numeric Expression text box. Click OK. (If nothing happens, select TRANSFORM> RUN PENDING TRANSFORM) Note that $ CASENUM is a system variable. The easiest method to find the list of all system variables is to open SPSS Help and search for $ casenum

- Restructure Data Wizard (Variables to Cases): Create Index Variables. In this step you determine whether index variables should be created. An index is a new variable that continuously identifies a group of rows based on the original variable from which the new row was created
indexvariables are variables in the current data that the wizard should use to create the new columns. The restructured data will contain one new variable for each unique value in these columns. Move the variables that should be used to form the new variable groups to the indexvariable(s) list. When the wizard presents options, you can also choose to order the new columns by index In the simplest case, a mean value index is calculated in SPSS using the syntax (File → New → Syntax). For sum indices, simply replace MEAN with SUM: COMPUTE AB01 = MEAN (AB01_01 TO AB01_10). EXECUTE. In the example above, all variables from AB01_01 to AB01_10 are calculated to form an index. If you want to offset individual items from a scale to form a sub-scale index, you specify them separated by commas
. A smart way to effectively investigate the correlations is to use factor analysis (as in my webinar) but also you can validate the variables / questions you want to use in your index by testing the value of Cronbach's alpha. If the value of Cronbach's alpha is high (above 0.7) then you can be sure of a reliable index between the variables you would like to use in the index Index form questions and discussions about working with SPSS from several (12) variables. For general statistical topics that are not related to SPSS, please use the statistics forum. The char.index function is one of the string functions, i.e. the tools for text replies. In short, as a result, it provides the position at which the needle first appears in the haystack. (SPSS actually uses this language!) In our application, we are not interested in the exact position - but we want to know whether the needle is actually in the. Now I have entered the data in SPSS, each item of all arcs is a variable (so a total of 127 variables). The item variables are ordinally scaled due to the rating scale, which is what I set in the variable view. I would now like to combine the items into sheets and scales (as in the questionnaires) in order to continue working with them (e.g. I would like to use the sheets to do a Spearman rank correlation)
. Basics in the operation of SPSS file types: .sav - data file .spo - output navigator = results of the SPSS procedures .sps command language Typical work steps in SPSS 1. Define variables. Check data for input errors 3. Transform data / create new variables / aggregate or merge data 4. Select cases / variable Is there a way to find the index of a variable in SPSS Python? For example, if one of my variables in the SPSS dataset is ID usually, I would be able to access the variable with the following code: varObj = datasetObj.varlist  Assuming that ID is the first column in my dataset. But what if the variable ID is lost somewhere in the middle of a dataset The sequence of the variables in SPSS is decisive! For this, the items in the variable list in SPSS must be sorted in such a way that they are between Zuf_APlatz1 and Zuf_APlatz8. However, there is still a problem with this formula: Only cases are included that have actually answered all 8 items
SPSS INDEX Function - SPSS Tutorial
ARCHIVED: In SPSS, how do I generate an ID variable that consecutively numbers each case in my data? This content has been archived, and is no longer maintained by Indiana University. Information here may no longer be accurate, and links may no longer be available or reliable. In SPSS, to generate an ID variable to consecutively number each case in your data, use the following command, which. As just shown, SPSS automatically sets the scale level to metric. But so that you don't have to select every single variable in order to change the measurement level individually, you can get around faster. The most elegant and fastest way to do this is with the SPSS syntax. So you write a command sequence and have it executed by SPSS. An index is a "variable" that is calculated from the values of several "indicators" for the "theoretical construct" to be examined. The aim of the index formation is to summarize the various indicators of the construct into one measured variable in order to be able to quantify the extent of the property to be examined for each investigation unit. Field Variables You can move all the nominally scaled variables for which you want to calculate Chi² statistics also more than two. We decide on the variable sex from our example data set. Assumption of equal distribution Under the assumption of equal distribution (see Section 9.1.1), the frequencies across all levels of the characteristic.
. All SPSS date-time variables, regardless of whether they're a date or a duration, are stored in SPSS as the number of seconds since October 14, 1582. This means that under the hood, date-time variables are actually integers Fig. 6. SPSS output for the Levene test for homogeneity of the variances. If, as part of the data analysis in SPSS, you compare the calculated significance with your probability of error of α = 0.05, the null hypothesis that the variances are equal cannot be rejected. Your test result does not speak against the requirement of homogeneity of variance software / index.html, log in with UniAccount) 1.2 Program structure IBM SPSS Statistics software comprises four program levels: data, syntax, output, script. These levels are each used as separate files. In order to save all processing steps, it may be necessary to save all four levels individually. • Data (.sav): The data level is used to enter and view the. Introduction to data analysis with SPSS Page: 4 What scale level do the following variables have: • Nationality • Telephone number • Intelligence quotient • School-leaving certificate • Income (queried in a list with 0 to less than 500 euros, 500 euros to less than 1000 euros, 1000 euros to less than 2000 Euro, 2000 Euro bis below Also note that in the output, SPSS tells us which variable were used to create the new variables, how many cases were in the long data set (called Cases In in the Processing Statistics table), how many cases are in the wide data set (called Cases Out), and how many index values were created. You can use this information to ensure that the reshaping went as desired. Example # 2: Two.
How do I create an index, ID or key variable? - SPSS
Restructure data in SPSS. You can analyze repeated measures data using various approaches, such as repeated measures ANOVA / GLM (the multilevel model) or the linear mixed model. Each of these approaches requires a different way of setting up the data in SPSS. Below are two different ways to set up repeated measures data, namely, the long format and the wide format. The long format uses multiple. The task of the analysis of variance is to identify the influence of qualitative variables (factors) on observable characteristics. In the model of the one-way analysis of variance, it is checked how great the influence of a factor is on the characteristics. If we want to compare whether the mean values of two variables are the same, we can do this with a t-test, which we already have in a. In other words creating dummy variables (but without a reference level) - e.g. Yellow vs. not yellow and then perform chi square. Next green vs. not green etc. till the end (with all the levels) If you want to create a single index variable, you should assess whether all of the relevant items form a scale. In SPSS, this can be done by calculating Cronbach's alpha. If you get a low value. Let's use SPSS string functions to get the first name and last name out of the name variable. We start by using the index function to determine the position of the first blank space in the name. We then use the substr function to extract the part of the name before the blank to be the first name, and the part after the blank to be the last name
indexing - Using SPSS Reference Variables and an Index to
- For index variable (s), enter the designator for the repeated measurement (in this case, it is TIME). Then click Next. 4) Select Yes to Sort the current data. 5) Click Finish and the data should be restructured to a wide format. Save the file as a transposed version
- Quick Steps. Click on Transform -> Compute Variable. Give your new variable the name ID in the Target Variable box. Click on All in the Function Group list, and then drag and drop $ Casenum into the Numeric Expression box at the top. Press OK. You'll be able to see your new ID variable in SPSS's Data View
- However, the index should indicate how many repetitions of the measurement a variable contains, e.g. the nth. So there is no point in simply numbering consecutively. Because the index has to start again at 1 every now and then. To make matters worse, the number of repeat measurements is not the same in all cases. See an example below. I have id_variable, index_variable has to be calculated
- al) want to recode, e.g. because you do not want to work with the specification of the age in years but with age groups. Let's take a look at this example: imagine you.
SPSS 'string function converts numeric values to string values. Its most basic use is compute s2 = string (s1, f1). where s2 is a string variable, s1 is a numeric variable or value and f1 is the numeric format to be used. With regard to our test data, the syntax below shows how to convert numeric_1 into (previously created) string_3 In the new window we find the variable label attribute for the new variable. After double-clicking on it, the following window appears: Illustration: Define value labels with SPSS. We now enter the desired labels for the numerical data, e.g. 20-29 for the number 1, etc. After entering all the changes to be carried out automatically, click on OK
Data restructuring wizard (variables to
- The easiest way to do this is to use the SPSS syntax. Open a new syntax window and enter the following instructions: IF beamter = 1 weighting = 0.76. IF civil servant = 0 weighting = 1.03. EXECUTE. Assuming a variable official in the data record with the corresponding characteristics, the new variable weight is now generated. Please remember to always specify decimal places with a point, otherwise SPSS will generate an error message
- IF (id EQ LAG (id)) first = 0. Even though the first command line makes SPSS compute the value 1 for variable first for each row of the data set, the second line will correct this and produce zeros in all rows but the first of each person. At the same time, we got round the 'very first row problem'
- Variables are just that - variable data points that you can adjust based on your SPSS analysis needs. Generally speaking they are not used in reporting. They are what you will see when you are trying to run your analytics. The variable labels are what will actually show up in the report
- Now, first of all, I had the frequencies spit out, this shows for the first time variable (Season 1) no value for 1 = none. Then I had Cronbach's alpha displayed for the three variables and that is probably okay, although it tells me that when I use the first variable take out, this value would improve. But this is not possible because I want to know how much you have seen in total. Now my question: now just have one.

- The item difficulties cannot usually be calculated directly in SPSS. The item difficulties can be calculated relatively easily by hand. For this, the following two points must be given: a) The coding of the k response levels goes from 0 to k 1 (in our example from 0 to 3)
- Errors can occur in SPSS both system-related and user-related. System-related missings, for example, are the result of conditional scaling in the course of filtering, the data cleaning of which SPSS automatically indicates with a point. On the user side, errors are on the one hand the result of a conscious definition of missing values. Typically, numerical values are selected here that do not appear in the data record, for example 101, -1 or -99
SPSS has a nice little feature for adding and averaging variables with missing data that many people don't know about. It allows you to add or average variables, while specifying how many are allowed to be missing. For example, a very common situation is a researcher needs to average the values of the 5 variables [SPSS wizard (e.g. for creating diagrams) correctly defined measurement levels for all variables and value labels for variables with ordinal or nominal measurement levels. So we start creating a new data sheet by defining the variables to be included there. 2.2.1 The data window tab. Variable view

- Some of the code files will generate the variables with missing values for old surveys if the survey does not have that variable. In addition, older surveys (mainly before 2000) do not have a wealth index in the dataset and the files would need to be merged with a WI file to include the wealth index. For anthropometry indicators, surveys before roughly 2006 need to be merged with a HW file to.
- Rules for a variable consist of a fixed set of tests that are applied to a single variable; B. Tests for values out of range. In the rules for a variable, the valid values can be expressed as a range of values or as a list of allowed values. Rules for multiple variables
- Median split calculator. Simply copy a variable from SPSS (as described further below) into the text field and have the transformation formula calculated. The number of cases is limited to 10,000. Any other cases will not be considered. The result is displayed directly below
- When you open SPSS you are in the SPSS Data Editor window. Now you have the possibility to go to the Data View and Variable View windows. In the Data View window, you can enter data yourself or read in data by using the options in the file menu. In (Figure 1.1) you see an example of a dataset in the Data View window.

- Running the SPSS syntax using an example. The following example shows you how SPSS syntax works. Suppose you have a data set with 7 columns for which you need to calculate the following values: mean for variables 1 to 3; Variance for variables 2, 4 and 5; Minimum and maximum for variables 5 to
- You must use the dummy coding in SPSS whenever you want to calculate a linear regression analysis with a categorical independent variable. Note that this situation is actually the only situation in which you have to do dummy coding in SPSS. In all other situations that occur during data analysis with SPSS, no dummy coding is necessary.We will demonstrate the topic of dummy coding in SPSS using an example.
- Calculate Cronbach's Alpha with SPSS. Cronbach's Alpha is quite easy to calculate with SPSS and only requires a few steps. It is important that we have named the variables logically or know which variables have been combined to form a scale. To carry out the reliability analysis, click on Analyze> Scale> Reliability analysis. This opens.
- Select variables and correlation coefficient and set the sigificance test Select variables on the left (age and grade) and use the arrow to move them to the VARIABLES field on the right. Select the correlation coefficient (here according to Pearson and Spearman). The grade is a special case here: assuming ordinally scaled grades, the Spearman rank correlation is calculated; one goes from.
- Variable names in SPSS used to be a maximum of eight characters long (this is different in the new versions, but in the interests of clarity and downward compatibility it cannot hurt to continue to adhere to this principle). Variable names should be as 'descriptive' as possible, i.e. give the user a clue as to what is stored in this variable. Variable names such as 'Value1', 'Value2' etc. are very confusing at the latest during the evaluation
Creating dummy variables in SPSS Statistics Introduction. If you are analyzing your data using multiple regression and any of your independent variables were measured on a nominal or ordinal scale, you need to know how to create dummy variables and interpret their results. This is because nominal and ordinal independent variables, more broadly known as categorical independent variables, cannot. Där visar SPSS vad vi skulle för värde på Cronbach's alpha ifall vi tog bort en enskild variable. Vi ser då att Cronbach's alpha skulle sjunka if all vi tog bort någon av frågorna fechld, fefam or fepresch, the vill säga frågorna somehow att göra med mödrar also work. Däremot ser vi att Cronbach's alpha skulle öka till, 690 ifall vi tog bort frågan. It is possible to group the variables and differentiate, for example, between male and female. We will learn exactly what that is in a later chapter. Just keep in mind that it is also possible to use this function to group. After the variables to be analyzed have been selected, one should still select the statistics: Settings. Recoding Variables in SPSS Statistics Introduction. The instructions below will show you how to recode variables. You can use recoding to produce different values or codes for a variable. 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. Before or after the actual data, you will find further variables in the data set. These are briefly explained below. Note: Some variables have to be activated explicitly when downloading the data. Note: The recording of browser data (browser, referrer, etc.) must be activated in the project settings before the data is collected
SPSS 16.0 is a comprehensive system for analyzing data. With SPSS, you can take data from almost any file type and use it to generate tabular reports, charts, graphs of distributions and trends, descriptive statistics, and complex statistical analysis. This manual, SPSS Base 16.0 User Guide, documents the graphical. For quantitative (scale) variables, the following data is also displayed: v Mean v Standard deviation v Number of extremely high and low values Statistics for indicator variables An indicator variable is created for each variable. This categorical variable indicates whether the variable is present or absent for an individual case. The indicator variables are used to calculate the Ta

A variable can be treated as ordinal if its values represent categories that have a natural order (e.g. degree of satisfaction with categories from very dissatisfied to very satisfied). Ordinal variables occur, for example, in attitude measurements (Zufrie Relative Weight Analysis is a useful technique to calculate the relative importance of predictors (independent variables) when independent variables are correlated to each other. It is an alternative to multiple regression technique and it addresses multicollinearity problem and also helps to calculate the importance rank of variables. It helps to answer which variable is the most important. In the example, an odds ratio of 1.03 is given in SPSS for the independent variable age (see Chapter 3: Logistic regression with SPSS). Those who were admitted to the intensive care unit and who are one year older than a reference patient therefore have, on average, a relative probability of survival that is approximately 3% lower.

SPSS is a very powerful statistical package, and it is very helpful for students to be familiar with it. However, many statistical procedures (including estimating averages, standard deviations and IQRs, and correlations) can be easily done using widely available software like MS-Excel, OpenOffice and GoogleDocs The below syntax will tell SPSS to examine the City variable then recode it to a numeric variable entitled City_CD and show the syntax generated to do so (in case you wish to repeat it later).

Analysis of multi-level data in the SPSS program The introductory presentation is limited to 2 levels, a metric dependent variable and cross-sectional data. Extensions (panel data and trend data) are then dealt with. Multilevel Analysis: Basics. Multi-level analysis Variables list. This gives you a blank histogram template. You now need to define what information will be displayed on the X-axis and the Y-axis of the graph. In this case, you want each bar of the histogram to represent a score on the Enjoyment scale. So, SELECT the Enjoyment variable from the Variables List and drag and drop it t With SPSS, this index can be determined over several levels: (a) Calculation of the item sum per person with SPSS. Figure 3-9: Calculating the item sum of the tasks per person (example PE scale, excerpt) (b) Transposing the data matrix and entering the total values. Figure 3-10: SPSS - for entering item mean values For this, the factor analysis and the associated SPSS module is the method of choice - or an analysis based on linear structural equation models, e.g. with LISREL. To determine measures of criterion validity or discriminant or convergent validity, the total score of the scale is required as an independent variable. This must be generated using transform-compute. For a According to Hair et al. (2013) for each row with a high condition index, you search for values above .90 in the Variance Proportions. If you find two or more values above .90 in one line you can assume that there is a collinearity problem between those predictors. If only one predictor in a line has a value above .90, this is not a sign for multicollinearity

- So if two independent variables correlate with each other with 0.8 or -0.8 or more, one should think about excluding one of the two from the analysis. VIF values and tolerance. Last but not least, and most resilient, in my opinion, is the calculation of the VIF values or the tolerance. VIF stands for variance inflation factor and is calculated for each independent variable in the coefficient table. It is an indicator of whether there is a high correlation between a.

- Since scratch variables are never part of the real data, you can be confident that you are not overwriting a permanent variable. 2. They are automatically initialized to 0 or blank, according to the type. 3. These variables are not reset when a case is read, so they are handy for constants and accumulators as well as things like loop indexes.
- In addition, different variables indeed must be named differently. (If they have the same names, SPSS will use the information from the first data set; this situation can be amended, however.) SPSS can deal with cases when one or two of these conditions are not met, however. The opportunities offered to deal with these situations allow for accomplishing fairly complex data management tasks with a few operations. Therefore, you may have a look at the following even if right now you don't have.
This defines which manifest variables (in SPSS the variables) belong to which subscale (latent variable). For example, to define aqr with the variables aq1, aq2, aq3 for the latent factor, 'aqr = ~ aq1 + aq2 + aq3' would have to be entered for Modelspec. In order for SPSS to correctly pass this command on to Lavaan, it is necessary to put this text in quotation marks. SPSS: Use index variable inside quotation marks.

How can you calculate a mean value from 3 items in SPSS? Very simple: compute means1 = (question1 + question2 + question3) / 3.execute.Assuming that the data record consists only of one person who has answered e.g. like this: Question 1: 3 Question 2: 4 Question 3: No answer (= missing value, n / a) Then SPSS does not provide a mean value for this person. This is only calculated if all values are valid.

Events related to the SPSS program package. For the sake of simplicity, we call the program SPSS or SPSS Statistics. Important SPSS commands and their correspondence in the menu system are presented here. Over the many beautiful menus there is the possibility to use SPSS for Windows commands directly. The correlation informs us about the degree of connection between two variables. See how to do it in SPSS or Excel. 68. Understanding and calculating covariance The covariance gives you information about the relationship between two metric variables. How to calculate it, we explain in the article. 36. Understanding and determining scale levels are categories that belong to us. SPSS is easy to learn and enables teachers as well as students to easily derive results with the help of a few commands. The implications of the results are fairly evident and are statistically valid. Using the software, one can conduct a series of studies quickly and effectively. If you are worried about conducting your data analysis on SPSS, here are a few guidelines and an overview of the.

One of the places that SPSS syntax excels at efficiency is when you're creating new variables. This is especially true when you're creating a LOT of new variables, but even one or two can be quicker if you write the syntax code instead of menus.
