Which of the following figures reflects the highest value of Karl Pearson's coefficient of correlation?

A+0.22

B+0.91

C-0.49

D-0.92 ✓ Correct

Correct answer: (D) -0.92

Explanation

Minus 0.92 reflects the highest value of Pearson's coefficient, judged by absolute magnitude.

Strength is measured by how far the value lies from zero, ignoring the sign.

Plus 0.22 is weak, lying close to zero.

Plus 0.91 is strong but slightly below 0.92 in magnitude.

Minus 0.49 is only moderate in strength.

Minus 0.92 therefore denotes the strongest, nearly perfect negative relationship here.
