Average error measures the average difference between the predicted values and actual values in a regression analysis. A positive value indicates that the model tends to overestimate the values, which means the model has low bias. On the other hand, a negative value indicates that the model tends to underestimate the values, which means the model has high bias. Therefore, option D is the correct answer.
