Four students in Ms. Alton's class shared the correlation coefficients derived from their data as follows:

- Student A: \( r = -0.87 \)
- Student B: \( r = -0.78 \)
- Student C: \( r = 0.79 \)
- Student D: \( r = 0.86 \)

Whose data had the strongest correlation?

A. Student A
B. Student B
C. Student C
D. Student D

Answer :

Considering the situation described above, the strongest correlation data is the "student a: r = –0. 87."

The correlation of variable is defined to be the strong correlation when the r-value is closer to +1 or -1.

Given that from the available options the r-value that is closer to +1 or -1 is that of student A which has -0.87, therefore, it is concluded that the Student A data had the strongest correlation.

Hence, in this case, it is concluded that the correct answer is option A. "Student A."
