The map shows the relationship between the percentage of students eligible for free or reduced-price lunches and Algebra I scores in Missouri school districts. The dark-shaded areas are those in which a higher percentage of students receiving such lunches is associated with lower end-of-course algebra scores. This statistically significant relationship is not found in lighter-shaded areas. Districts in white generally are elementary-only and have no Algebra I data.
