schools: schools data

In SDAResources: Datasets and Functions for 'Sampling: Design and Analysis, 3rd Edition'

Description

Math and reading test results from a two-stage cluster sample of tenth-grade students. An SRS of 10 schools was selected from the 75 schools in the population, and then 20 students were sampled from each school. These data are fictional but the summary statistics are consistent with those seen in educational studies.
