Exploratory Factor analysis - Process Factor Analysis - Interpretation of the factors
3 important questions on Exploratory Factor analysis - Process Factor Analysis - Interpretation of the factors
Which tables should we check to interpret the factors?
- Factor plot rotation
- Communalities (<.2 is not good, or <.5, given the research stage: when further, you should be less strict due to validity). The commonalities represents the extend to which the items are represented by the factor. So, stated differently: to what extend are the individual items relevant for the study?

Which table should we check for cross-loaders when VARIMAX rotation?
Rotated factor matrix.
Which table do we need to check when rotated OBLIMIN?
Pattern matrix and factor correlation matrix.
