6. Which of he following is NOT a consideration when naming factors?
- Common sense
- Theoretical considerations
- Applicability to a particular theory
- Sizes of factor loadings
7. In E.F.A, if commonalities are much smaller than 0.5 then the sample size must be more than...
8. In our pre-analysis checks of E.F.A, the KMO score should be less than what?
9. The absolute minimum amount of participants required for E.F.A is...
10. Gve an example of a method of oblique rotation
- Levene's
- Box's M
- Direct Oblimin
- Varimax
11. What is the problem with using the split half test to measure the internal reliability of an E.F.A?
- Not all data is on a ratio scale
- There are numerous different methods to split the data
- There is only one, largely unreliable method to split the data
- Measuring the data in this way greatly effects its statistical power
12. A psychologist finds that some of his eigenvalues have a difference of less than 0.2 across the same component. This is an example of what?
- Risk of cross - loading
- Nothing to worry about - no cross-loading
- Cross - loading
- Risk of skew
13. A psychologist finds that some of his eigenvalues have a difference of more than 0.3 across components. This suggests what?
- Cross-loading
- Risk of skew
- No cross-loading
- Risk of cross-loading
14. When utilising an E.F.A for dichotomous scores, the best method to assess internal reliability is what?
- Split-Half-Test
- KR-20
- Cronbach's Alpha
- Bi-Serial-Correlation
15. A researcher conducts a parallel analysis to aid in extracting factors from her E.F.A. Which factors should she extract?
- Any factors that have observed eigenvalues that are much less than 0
- Any factors that have observed eigenvalues greater than the randomly generated ones
- Any factors that have observed eigenvalues the same value as the randomly generated ones
- Any factors that have observed eigenvalues less than the randomly generated ones
16. What are the basic stages of the E.F.A analysis process?
- Pre - Analysis Checks > Extraction > Factor Naming > Rotation
- Pre - Analysis Checks > Rotation > Extraction > Factor Naming
- Pre-Analysis Checks > Extraction > Rotation > Factor Naming
- Pre - Analysis Checks > Factor Naming > Extraction > Rotation
17. In E.F.A, if commonalities are less than or equal to 0.5, and there are only a few factors, then the sample size must be
- Within 150 and 250
- Within 100 or 500
- Within 100 or 200

18. The ratio of items to factors in E.F.A should be....

- To establish causation between a large group of unrelated components
- To establish the confirmation of a known psychological effect
20. Give an example of a method of orthogonal rotation
- Direct Oblimin
- Levene's
- Varimax
- Box's M
