The purpose of this project is to analyze the relationship between test scores, school characteristics, and student demographic backgrounds for the California school districts. The data are based on all the 420 K-6 and K-8 districts in California with data available for 1998 and 1999. All the data were obtained from the California Department of Education (www.cde.ca.gov). The variables of this project are defined as follows.

 

TESTSCR     = The average of the reading and math scores on the Stanford 9        standardized test administered to 5th grade students.

STR                = The student- teacher ratio

                        AVINC           = The district average income in thousands of dollars

                                                            ELPCT          = The percentage of students that are English Learners, that is for       whom English is a second language

 

The project is in five sections based on (i) introduction, (ii) model, (iii) descriptive statistics (iv) empirical results and (v) conclusion.
