If the Pearson's correlation coefficient is positive the relationship coefficient is direct. If it is negative, it is inverse.

If is considerate to be strong if it is larger than 0.7

In this problem, we have that:

The Pearson's correlation coefficient was found to be .78. It is positive, and larger than 0.7. So the correct answer is:

A. Direct, strong
