Factor Analysis (Principal Components) Output

2. Initial Variables and their communalities
Principal Components (Factors)

3. Principal Components Extracted
Interpret the Initial Eigenvalues of and for factors 1 and 2.
What are the Eigenvalues after rotation?
Principal Components (Factors)

4. Principal Components (Factors)
Scree Plot
Based on the Scree Plot, does it make sense that 2 Factors were extracted out of the 5 possible factors?
Principal Components (Factors)

5. Factor Loadings (Correlations with the original variables)
How are the factor loadings for the
rotated component matrix
Different from the un-rotated one?
How would you interpret the
two factors that were extracted?
