Question

Suppose the correlation between the number of times couples go to the movies and the number of times they go out to dinner is +0.79. Among the following conclusions, which one is notconsistent with this computation?a. There is a strong positive correlation between the number of times couples go to the movies and the number of times they go out to dinner.b. The less often that couples go to the movies, the less often they go out to dinner.c. Because the correlation coefficient is less than 1.0, the association between these two variables is very weak and probably unreliable.d. The more often that couples go to the movies, the more often they go out to dinner

Answer 1

Answer:

.c. Because the correlation coefficient is less than 1.0, the association between these two variables is very weak and probably unreliable.

Explanation:

The option c contradicts the results from the computation in the question which says there is a positive correlation between number of times couples go to the movies and the number of times they go out to dinner. A positive correlation would mean that an increase in one variable is a cause of increase in the other. However the option claims the relationship is weak and unreliable, going against the apparent meaning of positive correlation here.
