dataset Measures

Individual items from the new scale to assess political trust and each of the validating measures are displayed first in SPSS (Variable View), followed by overall scores for the validating measures at the conclusion.

The overall scores generated by the data are averages. For example, if there were ten items, they were totaled up and then divided by ten. i.e., ((item1 + item 2.....item10)/10) You will need to calculate the overall score and/or factor scores for the new political measure, which will be dependent on the final result of your factor analysis.
