Question

Professor Miller has found the correlation between a person's "need for affiliation" (found by taking a test to determine the need to be with others) and the number of hours spent watching television is -0.69. He should conclude

A. there is not much of a relationship between the two variables because the r is negative.
B. the people who watch more television tend to have more need to be around others.
C. as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend more and more time watching television
D. as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend less and less time watching television.

Answer 1

The negative correlation between a person's need for affiliation and the number of hours spent watching television is explained. The correct conclusion for Professor Miller is identified, based on the correlation. The correct answer is Option D: as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend less and less time watching television.

Step-by-step explanation:

The correlation between a person's 'need for affiliation' and the number of hours spent watching television is -0.69. This negative correlation means that as the need for affiliation increases, the number of hours spent watching television tends to decrease.

Therefore, the correct conclusion for Professor Miller would be that as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend less and less time watching television.

Thus, option D, 'as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend less and less time watching television,' best illustrates the negative correlation between the need for affiliation and the number of hours spent watching television.The correlation between a person's need for affiliation and the number of hours spent watching television, as given, is -0.69. This figure indicates a negative correlation.

Option A is incorrect because a negative 'r' does not imply a lack of relationship; it indicates that the two variables move in opposite directions. Option B is incorrect because it contradicts the negative correlation. Option C is also incorrect for the same reason.

The correct answer is Option D: as we observe people with higher and higher need for affiliation, we see a tendency for those people to spend less and less time watching television. This is because a negative correlation indicates that as one variable increases, the other decreases.
