The data in Exhibit 1-3 show that as the number of years of education increases, the median income also increases. This relationship is positive, meaning that the two variables are moving in the same direction. The data also show that the relationship is nonlinear, meaning that the increase in median income is not constant for each additional year of education. Therefore, the correct answer is A) downward; (nonlinear)curve.
