head of staffing for BabyBots, a manufacturer of small robots. The employee is surprised to learn that the company had never validated the manual dexterity test it uses to assess job candidates for its manufacturing jobs. The employee decide to do a concurrent validation study and administer the test to 30 manufacturing workers. Their scores are reported in Table A, along with their ages, sex, race, and job performance ratings. The employee also calculated the correlation between the manual dexterity test and job performance to assess the test's validity. The employee then examined the relationship between employees' test scores and their performance ratings. The results of this analysis are shown in Table B.

Table A

Employee Data

Performance rating: 0 = 0% efficiency, 100 = 100% efficiency

Sex: 0 = male; 1 = female

Race: 0 = Hispanic; 1 = White; 2 = Black

Test	0.12	1.00
Job Performance	0.18	0.86	1.00

Note: Correlations underlined and in bold indicate statistical significance at a level of p < .05.

Questions:

1. What kind of relationship exists between employees' scores on the manual dexterity test and their performance ratings?

1. Assume that only candidates scoring at least 41 on the manual dexterity test were hired (21 of the 30 people in this sample). Would the use of this test have led to evidence of adverse impact based on sex or race? The relevant data on the 21 people exceeding the cutoff are below.

Above a Cutoff of 41
Sex	Count Above 41	Total Count	Percent
Males (0)	8	15	53.3
Females (1)	13	15	86.7
Total	21	30	70.0

Above a Cutoff of 41
Race	Count Above 41	Total Count	Percent
Hispanic (0)	7	10	70.0
White(1)	7	10	70.0
Black (2)	7	10	70.0
Total	21	30	70.0

1. Suppose a candidate scored 45 on the manual dexterity test. The regression equation predicting job performance using the manual dexterity test is:

32.46 + (1.23 Manual dexterity test score)

What is the candidate's predicted job performance?

1. Given the validity results you found, would you recommend use of this test as a selection device? If so, how would you use it?
