The Effect of Per-Student Expenditure on Percentage of Students Satisfactory in Mathematics
MetadataShow full item record
This study investigates whether per-student expenditure is correlated with the quality of education, using the percentage of students satisfactory in mathematics as an analog. Although the simple linear regression model did not find a significant relationship, all multiple regression models indicated that the correlation was significant and positive. In addition, the two variables unique to this study, read4 and lunch, were the most important secondary independent variables. However, more practical conclusions can be made when models do not include read4. A model with only per-student expenditures and lunch was found to explain a large amount of variation in our dependent variable. Overall, we conclude that increasing expenditures per student can increase the percentage of students satisfactory in 4th grade math and the overall quality of education at a school.
