With Label you can give the variable a good name. SPSS’s heart is written in FORTRAN and variable names in FORTRAN used to be limited to eight characters which frequently makes it awkward to have good name for the variable. The Label is left over from early FORTRAN days.
Qualitative variables need to be Numeric and they are handled with the Values attribute - as we’ll see shortly! The Width and Decimals attributes are just to format the appearance of the numbers in the Data View sheet totally not critical. Having this set to String will cause errors if you are trying to use the variable as a qualitative variable (selection is via a pull down menu that appears when you click on a cell). Type should be Numeric if you want to use the variable in any kind of statistical calculation. The Name attribute gives the name of the variable as it appears at the top of the columns in the Data View window. The big exception is the Values attribute - it’s important and we’ll come back to that after a quick look at the other attributes. You can usually leave most of the attributes as they come by default. Either way, you’ll end up in the Variable View window that looks like : SPSS screenshot © International Business Machines Corporation.Įach line in the Variable View window lists the attributes of the variables listed in the Data View window. This is done by either double clicking on the variable name at the top of a column or by clicking the “Variable View” button at the bottom. As we said, we only need one independent variable for univariate tests. independent or dependent) so you need to keep track of their meaning yourself. SPSS doesn’t care what kind of variables you define (e.g. To fix ideas, suppose the subjects are people.
In Psychology, the subjects (“participants”) are generally people but they could also be rats or schools or cities or whatever. The rows represent individual subjects in the study.

So many of the first SPSS lessons will be about how to combine multiple variables into one variable for analysis.īack to the Data View window and the data matrix. We are only going to learn how to deal with one dependent variable at a time. This textbook covers univariate statistics. We need to learn a whole lot of basics before we can competently use multivariate statistics. This is the first trap that people who try to use SPSS fall into - they collect data, put the data into SPSS and then go looking for an appropriate statistical test using help or the built-in “statistics coach”. The Data View window is arranged in the form of a “data matrix”, which is an essential structure for multivariate statistics. But let’s talk about what’s on the Data View window before we look at the other two windows. You can get to the Variable View window either by clicking on the Variable View tab at the bottom of the window, or by double clicking one of the column headings (the “variable name”). The other two windows are the “Variable View” window and the “Output” window. It is one of the three windows you will see when you use SPSS. You should see: SPSS screenshot © International Business Machines Corporation.
