If you switch to the Variable View on the main screen you will see that bothasp has appeared at the bottom. 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. When deciding what type of graph to produce, you first need to think about (1) the type of data you have collected: interval, ordinal or nominal data. Before you start stacking you should work out: 1. How do I create an index, ID or key variable. When creating a new, aggregated data file, all break variables are saved in the new file with their existing names and dictionary information. In the "Restructure" window, select Restructure selected variables … You should now see the following dialogue box. Creating dummy variables in SPSS Statistics Introduction. You can use this information to ensure that the reshaping went as desired. Factor scores are essentially a weighted sum of the items. As explained in the "Get File" and "Save File" chapters, existing variables can be renamed either when retrieving or saving data. ... but you are interested in the latent construct that is indicated by a number of variables. To initiate our index construction, we need to create the new variable so that SPSS will know where to put the results of our work. Step 2 Double-click the name of the file you wish to open, and then click "Open." There is an alternative approach as well that I have recently used from Michael Anderson (2005) on Multiple Inference and Gender Differences in the Effects of Early Intervention: A Reevaluation of the Abecedarian, Perry Preschool, and Early Training Projects.
