Answer

Explanation:

Step1: Recall correlation - coefficient property

The strength of a correlation is determined by the absolute value of the correlation coefficient $r$. The closer $|r|$ is to 1, the stronger the correlation.

Step2: Calculate absolute - values

For Student A: $| - 0.87|=0.87$. For Student B: $| - 0.78| = 0.78$. For Student C: $|0.79|=0.79$. For Student D: $|0.86|=0.86$.

Step3: Compare absolute - values

$0.87>0.86>0.79>0.78$.

Answer:

Student A
