Suppose that the calculated value of r between cognitive ability and job performance is 0.73. How much variation in job performance is explained by the variation in cognitive ability?

53.28%

Explanation:

The correlation coefficient (r) between cognitive ability and job performance is provided as 0.73. Therefore, the coefficient of determination is calculated as follows:

Coefficient of determination = r² = 0.73² = 0.5329

Therefore, 53.28% can be concluded to be the variation in job performance as explained by the cognitive ability.
