ggridges: mean test score by subgroup and test by region

Mean test score above or at proficient grouped by regions in the United States

Rebecca

Research Question:

How do high school students’ subgroup makeup (i.e., Race/ethnicity, Male vs. Female, economically disadvantaged, Limited English, Migrant status, Disability status, and Homelessness) and mean test scores in math and reading differ among states/regions?

• Design choices:
  • Lightened the colors of the ridge lines so that they are more transparent.
• Findings: There are no clear regional differences. However, patterns among subgroups showed that children with disabilities and English learners scored lowest in test score proficiency. Thus, more resources should be provided to these students so they can have greater academic success.
