Your team is assessing the criterion-related validities for a scored structured interview (StructuredInterview) and work sample assessment (WorkSample) in relation to overall job performance (JobPerformance) for a Software Developer job. You have already established that both selection procedures are significantly associated with job performance by themselves (as evidenced by correlation analyses), and now its time to assess whether there is any redundancy between the two selection procedure variables (i.e., very large correlation), if both are still significantly associated with job performance when specified in the same regression model, and what the collective criterion-related validity of the selection procedures are in terms of the R-squared value. Please respond to the following questions as if you were explaining the data to a manager who is not familiar with statistical terminology.

• Is there any concerning amount of redundancy between scores on the structured interview and scores on the work sample? How do you know?
• Are both selection procedure variables still significantly associated with job performance when specified in the same multiple linear regression model? How do you know?
• What is the R-square value for the model? What does this value indicate?
• Do you recommend that the organization use both selection procedures in the future? Why or why not?

Note: For the purposes of this exercise, imagine that your HR team is revamping the selection procedures for the Sales Associate job. Your team has conducted a concurrent validation study in which Sales Associate job incumbents complete the following selection procedures: proactivity assessment, emotional intelligence inventory, and situational judgment test (SJT). With regard to the criterion (outcome) of interest, the job incumbents were also assessed in terms of their customer service job performance.
