Asian and white students lie above it, and Hispanic, Native American and Black students below; not disadvantaged students lie above it and disadvantaged students below. Each mean weights counties by the group's tests, with a 95% interval from a bootstrap over states. Counting each county once pulls every level toward zero, and the table gives both.",

    "Each group's mean covers only the counties that report the group, and the number of counties differs by group (it is in each row's tooltip), so the groups are not measured in the same places. SEDA takes the groups from state reports. Race and ethnicity follow the federal categories, which are mutually exclusive, so Hispanic students of any race form their own group and the Asian, Black, white and Native American groups exclude them. States define economic disadvantage themselves."
