This data set is a stratified version of the previous "apiclus2" data. It is derived from the Academic Performance Index computed for all California schools based on standardized testing of students. The original data sets contain information for all schools with at least 100 students and for various probability samples of the data. The design is 1-stage cluster sampling with clusters of unequal sizes. An SRS of 200 districts is selected (psus) from the 755 districts in the population. All schools within district are selected (ssus).
