Then select the "California Test Score Data Used in Chapters 4-9" and read the data either into Excel or STATA (or another statistical program).First run a regression where the dependent variable is test scores and the independent variable is the student-teacher ratio.Record the regression R2.Then run a regression where the dependent variable is the student-teacher ratio and the independent variable is test scores.Record the regression R2 from this regression.How do they compare?
