Question
A human resources manager thinks that employees who work in a more open work environment are more satisfied with their jobs than those who work in a less open work environment. She selects a random sample of 400 employees and measures their work environment (high-more open, low-less open) and job satisfaction (high, low). He learns that 140 of the 200 employees who work in a more open work environment report high job satisfaction and that 100 of the 200 employees who work in a less open work environment report low job satisfaction. He wants to know whether he should make the work environment more open or less open. Note 1: X = Independent variable. Y = Dependent variable. Note 2: H = High, L = Low.
Which of the following data is appropriate for addressing this management challenge?
A. X = H,L,L,L,H,H,L,H,H,H,......Y = H,L,L,H,H,L,H,,L,L,H,.....
Which can be summarized as:
Mean satisfaction scores by Environment
Mean Standard deviation
More Open Work Environment (H) 140 8
Less Open work Environment (L) 80 10
B. X = H,L,L,L,H,H,L,H,H,H,...... Y = H,L,L,,H,H,L,H,L,L,H,.....
Which can be tabled as:
Work Environment (X)
L H
Job Satisfaction (Y) L 100 60
H 100 140
C. X = 1,30,21,40,32,40,35, ....... Y = 3,2,4,5,6,7,3,4,5,6,7,8,.......
Which can be reduced to:
Y = 100 +20X
D. X = 1,30,21,40,32,40,35, ....... Y = 3,2,4,5,6,7,3,4,5,6,7,8,.......
Which can be reduced to:
Mean = 140, Standard deviation = 40.

Explanation / Answer
Of the 4 choices, the following data is appropriate for addressing this management challenge:
Answer : B)
It's important to look at what's stated in the question.
X = work environment and Y = satisfaction
In both cases, H = high and L = low. There's no numerical equivalent at all for any of these scores. We will have the data only in terms of H and L. This basic idea rules out A, C and D, which somehow have numbers in the data points.
Cheers!
