Measures in the dataset In SPSS (Variable View) the demographics are presented first, followed by individual items from the new scale to measure political trust and each of the validating measures, and overall scores for the validating measures are presented at the end. The overall scores that have been created in the data are averages. For example, if there were 10 items, they were all added together and then divided by 10. i.e., ((item1 + item 2…..item10)/10) You will need to create the overall score and/or factor scores for the new political measure, and this/these will be based on the final result you get for your factor analysis.
