Creating Factor Scores Variables in the Data Source

Once the analysis is complete, it is often desirable to assign scores to each respondent to indicate where that subject stands on the retained factors. In our example, these were the Factor scores of “Facilities”, “People” and “Food and Drink” . With this done, these factor scores could be used either as predictor variables or as criterion variables in subsequent analyses.

To create the factor scores on the data source:

1. Click on the Create Factor Scores button in the top dialog.

The Create Factor Scores overlay opens .

2. Select the appropriate calculation run that you wish to use for the basis of the variable creation, then input the name that you wish to label each factor score retained.

Once the generation task has been completed, this will create a new selection of variables available in the Data Source toolbox. Under the Factor Scores folder, a new sub folder will be created for each set of factor scores created. This folder will include the name of the factor analysis object, and the calculation run name. The factors will be present in sub folders as numeric variables .

Using Factor Scores in Subsequent Analysis

As mentioned earlier, these factor scores can then be used for additional analysis purposes, for example in linear regression calculations or aggregate tables .
