question 4

Short Answer

TABLE 13-13
In this era of tough economic conditions, voters increasingly ask the question: "Is the educational achievement level of students dependent on the amount of money the state in which they reside spends on education?" The partial computer output below is the result of using spending per student ($) as the independent variable and composite score which is the sum of the math, science and reading scores as the dependent variable on 35 states that participated in a study. The table includes only partial results.

-Referring to Table 13-13, what percentage of the variation in composite score can be explained by the variation in spending per student?
