Will you please share MCQ question of this doubt.
here is ques
Since there is a very high inverse relationship, the value of the coefficient of correlation will be - 0.80. Thus, option 4 is the correct answer.
The correlation coefficient lies between -1 to +1. +1 being perfectly positive correlation, -1 being perfectly negative (inverse) correlation, 0 being no correlation at all. So for highly inverse correlation would be the value of -0.80. Hope this will help you.
