Question

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? student a student b student c student d.

Answer 1

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."
