A positive correlation between two factors indicates that the factors
A. are NOT necessarily related.
B. are strongly related.
C. decrease proportionately.
D. tend to increase or decrease together.
Answer:D
A positive correlation between two factors indicates that the factors
A. are NOT necessarily related. B. are strongly related. C. decrease proportionately. D. tend to increase or decrease together.
Explanation: D) A positive correlation indicates that two factors increase or decrease together. As one increases so does the other; as one decreases so does the other. Therefore, the two factors for a positive correlation vary in the same direction. If the correlation is negative, one factor increases while the other factor decreases. [Note that, unless it is perfect, the correlation only suggests a tendency or pattern.]
