If the correlation coefficient is 0.790, what is the explained variation?
A. 37.6%
B. 62.4%
C. 79%
D. 21%
62.4%
To find the explained variation, you can square the correlation coefficient (r) and multiply it by 100%.
In this case, the correlation coefficient is 0.790.
So, the explained variation is (0.790)^2 * 100% = 0.624 * 100% = 62.4%.
Therefore, the answer is B. 62.4%.
To find the explained variation given the correlation coefficient, you need to square the correlation coefficient and multiply it by 100 to convert it into a percentage.
In this case, the correlation coefficient is 0.790. To find the explained variation, we square the correlation coefficient:
(0.790)^2 = 0.6241
Then, we multiply it by 100 to convert it into a percentage:
0.6241 * 100 = 62.41%
Therefore, the explained variation is approximately 62.41%.
The closest option is B. 62.4%.
