1. How do you interpret the reliability results for the clerical test and work sample? Are they favorable enough for the company to consider using them “for keeps” in selecting job applicants?
A. Clerical Test
Coefficient alpha is high (.85, .86). This is a positive sign.
Test-retest reliability is also high (.92).
B. Work Sample (T)
Inter-rater agreement is relatively high (88%, 79%)
C. Work Sample (C)
Inter-rater agreement is okay (81% , 77%)
Conclusion: The results above suggest that the three tests have adequate reliability
2. How do you interpret the validity results for the clerical test and work sample? Are they favorable enough for the company to consider using them “for keeps” in selecting new job applicants?
A. Clerical Test
Correlations with work sample (T) and work sample (C) are low and n.s.
Criterion-Related Validity
Significant correlations with error rate (negative) and speed (positive).
Non-significant correlations with complaints
B. Work Sample (T)
High correlation with work sample (C).
Criterion-Related Validity
Correlations with error rate (negative) and speed (positive) are not significant.
Correlations with complaints high and significant.
C. Work Sample (C)
High correlation with work sample (T).
Criterion-Related Validity
Correlations with error rate (negative) and speed not significant.
Correlations with complaints significant.
Conclusion: The results above suggest that the clerical test and either the work sample test (T) or (C) should be used in the selection process for CSRs. The work sample tests produce similar results; this suggests that they are redundant. The clerical test is a good predictor of a different criteria (i.e., error rate and speed). Thus, using both the clerical test and one of the work sample test appears to be the best combination of predictors.
