Which of the following correlation coefficients represents the strongest relationship between two variables? a. +0.30 b. +0.75 c. +1.3 d. -0.85 e. -0.05

d. -0.85

Step-by-step explanation:

Since we know that ,

The value of strong correlation coefficient r, lies between the absolute value of 0.75 to 1.

From all the given options (a. +0.30 b. +0.75 c. +1.3 d. -0.85 e. -0.05) ,

The absolute value of -0.85  (|-0.85|=0.85) is nearest to 1 among all.

(Note : Negative correlation coefficient mean there is negative association between the variables.)

Therefore , the correlation coefficient represents the strongest relationship between two variables is -0.85  .

Hence, the correct answer is  d. -0.85 .
