Short Answer: In the space given, answer the question. Item points are given with each item. Use the diagram below to answer questions 9 through 12. Dependent Variable- XI (independent variable 1) X2 (independent variable 2) 9. Which letter represents the unique beta weight for XI? (2 points) 10. Which letter represents the non-overlap area for X17 (2 points) 11. Assuming a standard regression, which letter represents ambiguous overlap? (2 points) 12. Assuming a sequential or hierarchical regression, which two letters represent the overlap area eliminated (controlled) before identifying the unique contribution of the variable of interest? (3 points) 13. How are unstandardized and standardized betas different? (3 points) 14. In interpreting output when you have more than one IV measured on different scales, you should interpret the standardized betas? Explain why. (3 points)
