Working with the Output Viewer The Output Viewer collects your statistical tables and graphs, and gives you the opportunity to edit them before you save or print them.
The point of this example is that one or both variables may have more than two levels, and that the variables do not have to have the same number of levels. The tables pane on the right is what is actually saved in the.
You can get the hsb data file by clicking on hsb2. Why is the Mann-Whitney significant when the medians are equal? The Label attribute allows you to give each variable a longer description that is displayed in place of the variable name, analogous to value labels for data values.
To save precious computer time an 'edit' run could be done to check command syntax without analysing the data. SPSS Statistics is available under either an annual or a monthly subscription license.
Hidden objects are not printed, but are saved with the output file. Typically you start your SPSS session by opening the data file that you need to work with.
