Details

There are n=133 average test scores for schools in the K=6 largest cities. The test score offers a standardized measure of academic achievement. The purpose of the study is to investigate if there is a relationship between academic achievement, as measured by the test, and poverty. It is expected that students from economically disadvantaged backgrounds will do less well. Data on the average income in the school district was not available so a proxy variable for poverty was used. The percentage of students who received subsidized meals was available so this was used as the "Poverty" variable.
