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...

  • 250
  • 500
  • 100
  • 200

8. In our pre-analysis checks of E.F.A, the KMO score should be less than what?

  • 0.2
  • 0.8
  • 0.5
  • 0.7

9. The absolute minimum amount of participants required for E.F.A is...

  • 150
  • 100
  • 500
  • 250

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

  • 4:3
  • 4:1
  • 5:1

19. Describe the purpose of Exploratory Factor Analysis...

  • To explain patterns of correlations in a smaller number of variables
  • To explain the extent with which measured variables and their co-variability can be explained by a smaller number of variables
  • 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
