Suppose you're studying levels of job stress and measures of job efficiency in a nursing home. Your hypothesis is that increasing job stress appears to lead to reduced job efficiency. In that case, job stress is the _______ variable.
A. correlated
B. empirical
C. dependent
D. independent

Respuesta :

The correct answer is letter A.

Job stress is a correlated variable. Job efficiency and job stress are correlated variables in this study because the existence of each would result to the other. This is how their relationship works, that when job stress is increased, job efficiency is decreased, and when job stress is decreased, job efficiency increases. 

The correct answer is D. Independent
