Suppose you’re studying levels of job stress and measures of job efficiency in a nursing
home. Which one of the following statements best represents a data comparison that
demonstrates a positive correlation?
A. As job efficiency increases, stress levels decline.
B. As stress levels increase, job efficiency increases.
C. As job efficiency decreases, stress levels increase.
D. As stress levels increase, job efficiency declines.
I think it is A because job efficiency is a positive thing while stress levels are negative. I am confused though about the difference between A and C. They are saying almost the same thing. All help is appreciated. Thank you in advance.
