Question

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 stress levels increase, job efficiency increases.
B. As job efficiency decreases, stress levels increase.
C. As job efficiency increases, stress levels decline.
D. As stress levels increase, job efficiency declines

Answer 1

B. As job efficiency increases, stress levels decline (THIS IS WRONG)I think its between A. As job efficiency decreases, stress levels increaseD. As stress levels increase, job efficiency increases

Answer 2

Answer: Hello mate!

You are studying the relationship between levels of job stress and measures of job efficiency.

now, we want to describe a positive correlation.

A correlation between two quantities, A and B, is A = kB

where k is a constant.

If the correlation is positive, means that when A increases also increase B, and then k is a positive number.

This means that, in our case, when job stress increases, job efficiency also increases.

Then the right answer is A "As stress levels increase, job efficiency increases."
