If a nurse researcher found that older patients asked fewer questions before surgery than younger patients, the relationship would be described statistically as:
a. negative.
b. null.
c. positive.
d. random.
ANS: A
In a negative relationship, a high score on one variable is related to a low score on the other variable. In this example, the older the person, the fewer questions they asked and the younger the patient, the more questions they asked. The relationship goes in different directions. As one relationship goes down (older age and fewer questions), the other goes up (younger age and more questions).
Null means that there is no difference.
Positive relationships mean that as the score on one variable goes up, the score on the other variable goes up also.
A random relationship would imply a low or near-zero correlation.
