The percentage of variation in baseball skills that would be accounted for is 0.3 x 100%, or 30%.

The validity coefficient is a measure of how well a test predicts performance. It measures the strength of the relationship between the scores on the test and the scores on the performance measure. To calculate the percentage of variation in baseball skills that would be accounted for, multiply the validity coefficient by 100%. In this case, the validity coefficient is 0.3, so the percentage of variation in baseball skills that would be accounted for is 0.3 x 100%, or 30%.

0.3 x 100% = 30%
