Answer: 81% of the variance in dependent variable is explained by this correlation .
Explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say
of the variance in Y is explained by Variable X.
Given: r= 0.90
![(0.90)^2= 0.81](https://img.qammunity.org/2022/formulas/mathematics/high-school/t91skq99eb32x74qbyez73f5o4vdt0m474.png)
So, 81% of the variance in dependent variable is explained by this correlation .
